Answer the following questions. Use Equation Editor when writing mathematical expressions or equations. First, save this file to your hard drive by selecting Save As from the File menu. Click the white space below each question to maintain proper formatting.

 

1. You have recently found a location for your bakery and have begun implementing the first phases of your business plan. Your budget consists of an $80,000 loan from your family and a $38,250 small business loan. These loans must be repaid in full within 10 years.

a) What integer would represent your total budget

 

b) Twenty-five percent of your budget will be used to rent business space and pay for utilities. Write an algebraic expression that indicates how much money will be spent on business space and utilities. Do not solve.

 

c) How much money will rent and utilities cost Explain how you arrived at this answer.

 

d) Suppose an investor has increased your budget by $22,250. The investor does not need to be repaid. Rather, he becomes part owner of your business. Will the investor contribute enough money to meet the cost of rent and utilities Support your answer, and write an equation or inequality that illustrates your answer.

 

e) This equation illustrates your remaining funds after paying for rent and utilities. How much money is left Explain how you arrived at your answer.

 

$38,250 + $80,000+ $22,250-0.25($80,000 + $38,250) =

¬

 

2. You are trying to decide how to most efficiently use your oven. You do not want the oven running at a high temperature when it is not baking, but you also do not want to waste a lot of time waiting for the oven to reach the desired baking temperature.

 

The instruction manual on the industrial oven suggests your oven temperature will increase by 45 degrees Fahrenheit per minute. When the over is initially turned on, the temperature is 70 degrees Fahrenheit. What will the temperature of the oven be after 7 minutes Write an expression and explain how you arrived at your answer.

 

 

3. In your industrial oven, you bake two baking sheets with 12 scones each, two baking sheets with 20 cookies each, and one baking sheet with 2 scones and 10 cookies.

 

a) Write an expression that illustrates the total cost of all baked goods in the scenario above using the variable s to represent the cost of scones and the variable c to represent the cost of cookies. Simplify your expression by combining like terms.

 

b) Suppose you have decided to price the scones at $2.28 each and the cookies at $1.19 each. How much total revenue would result from selling all the scones and cookies baked in the oven at one time

 

c) Yesterday your store earned $797.30 just from the sale of cookies. Write and solve an equation that represents how many cookies were sold.

 

4. Your profit P is determined by subtracting the cost C (the amount of money it costs to operate a business) from the revenue R (the amount of money you earn from selling your product). Profit can be represented algebraically by the equations

 

Profit=Revenue-Cost

OR

P = R – C

 

a) Rewrite the formula to solve for C.

 

b) Suppose your profit for one day is $1,281, and the cost of running the business for the day is $1,463. What is the revenue for that day Explain your answer.

Project 3 instructions

 

Based on Larson & Farber: sections 5.2-5.3

To obtain the data:

 

  1. Go to this website.
  2. Set the date range to be 1/2/2014 to 1/2/2015.
  3. Click “update”. 
  4. Click the link on the right that says Download to Spreadsheet

 

This project will only use the Closing Values. Assume that the closing prices of the stock form a normally distributed data set. This means that you need to use Excel to find the mean and standard deviation and then use those numbers and the methods you learned in sections 5.2 and 5.3 of our text book for Normal distributions to answer the questions.

 

Complete this assignment within a single Excel file. Show your work or explain how you obtained each of your answers.  Answers with no work and no explanation will receive no credit.

 

1.      If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed at less than the mean for that year? Hint: You do not want to calculate the mean to answer this one. The probability would be the same for any normal distribution. (5 points)

 

 

 

2.      If a person bought one share of Google stock within the last year, what is the probability that the stock on that day closed at more than $550? (5 points)

 

3.      If a person bought 1 share of Google stock within the last year, what is the probability that the stock on that day closed within $45 of the mean for that year? (5 points)

 

 

 

4.      Suppose a person within the last year claimed to have bought Google stock at closing at $500 per share. Would such a price be considered unusual?  Be sure to use the definition of unusual from our textbook. (5 points)

 

 

5.      At what prices would Google have to close at in order for it to be considered statistically unusual? You should have a low and high value. ?  Be sure to use the definition of unusual from our textbook. (5 points)

 

6.      What are Quartile 1, Quartile 2, and Quartile 3 in this data set? Use Excel to find these values.  This is the only question that you should answer without using anything about the Normal distribution. (5 points)

 

7.       Is the normality assumption that was made at the beginning valid? Why or why not? Hint: Does this distribution have the properties of a normal distribution as described in our textbook? It does not need to be perfect.  Real data sets are never perfect.  However, it should be close. One option would be to construct a histogram like we did in Project 1 and see if it has the right shape.  If you go this route, something in the range of 10 to 12 classes would be a good number. (5 points)

 

 

 

 

 

Correct mean: 1.5 points

Correct SD: 1.5 points

Correct date range: 2 point

 

 

Submit your work through the assignment link by 11:59 p.m. (ET) on Monday, 2/16.Please make sure to show all steps. If you use Excel to help find the answer, explain in words what you do.  Note that you must do this project on your own—you may not work with other students. You are always welcome to ask your instructor for help.

Administrator Competencies and Paths to Leadership

Name of Student:

Institutional Affiliation:

Question 1: Administrator Competencies

The whole issue regarding the management, planning, and other administrative role with regards to the management of young people is a broad concept. The National Association for the Education of Young Children is an association that is in charge with the administration of knowledge and other administrative duties to the young people. In light of the above, there is a very narrow line that separates the management knowledge and skills and early childhood knowledge and skills. Notably, the two concepts largely overlap both conceptually as well as in practice.

To begin with, management of knowledge and skills is largely premised on the ability of administrators to coin out knowledge out of day to day activities. The same is the case when it comes to the management of the early childhood knowledge and skills. Conceptually, the two are similar in the sense that they both revolve around scouting in some source of information in order to arrive at some steady yet very reliable and solid conclusions that can steer their administration to a higher level of achievement. This brings to the fore the link that exists between the concept of early childhood knowledge and skills as well as management knowledge and skills.

Nonetheless, there is a practical relationship between management knowledge and early childhood knowledge and skills. It is noteworthy to take into consideration the fact that the administrators who are in charge of management are the ones who are more likely to use the same knowledge they acquire in the various fields of operations to pass to the young children in kindergarten and other learning institutions for the young people.

 

 

Question 2: Paths to Leadership

 

            NAEYC’s Code of Ethical Conduct: Supplement for Early Childhood Adult Educators is a document that act as the guideline for early childhood educators. The guideline is core to the practice as it offers the various sets of moral obligations among the practitioners. It is therefore important that such guidelines are implemented to the letter by the various administrators who are in charge. This way, it is easier to manage the moral and ethical behaviors of the various managers.

            Furthermore, the ethical guideline is consistent with my personal pathway of the inside syndrome. In this pathway, I am of the strongest conviction that moral obligations should be inwardly generated rather than depend in the various guidelines to restrict the moral and ethical orientation of an individual (Bilha, 2012). This means that it is important that one act morally out of his or her personal will rather than acting like so out of some external or outward pressures; without which, such a person cannot be in a position to act in a way that is regarded as moral or ethical by the rest of the society.

            Pursuant to the NAEYC’s Code of Ethical Conduct, the provision outlined significant approaches that could be implemented in order to avert the ethical and moral dilemmas that plague the leadership and management of an organization (Don, 2011). One of the challenges that are sought by the guideline is that of the ideals and principles. This way, it is possible that readers get a lot more than is obvious.

Assignment #1: Case Problem “Julia’s Food Booth” 

 

Complete the “Julia’s Food Booth” case problem on page 109 of the text. Address each of the issues A – D according the instructions given. 

 

•(A) Formulate and solve an L.P. model for this case.

•(B) Evaluate the prospect of borrowing money before the first game.

•(C) Evaluate the prospect of paying a friend $100/game to assist.

•(D) Analyze the impact of uncertainties on the model.

 

 

 

Julia is a senior at Tech, and she’s investigating different ways to finance her final year at school.  She is considering leasing a food booth outside the Tech stadium at home football games.  Tech sells out every home game, and Julia knows, from attending the games herself, that everyone eats a lot of food.  She has to pay $1,000 per game for a booth, and the booths are not very large.  Vendors can sell either food or drinks on Tech property, but not both.  Only the Tech athletic department concession stands can sell both inside the stadium.  She thinks slices of cheese pizza, hot dogs, and barbecue sandwiches are the most popular food items among fans and so these are the items she would sell.

 

Most food items are sold during the hour before the game starts and during half time; thus it will not be possible for Julia to prepare the food while she is selling it.  She must prepare the food ahead of time and then store it in a warming oven.  For $600 she can lease a warming oven for the six-game home season.  The oven has 16 shelves, and each shelf is 3 feet by 4 feet.  She plans to fill the oven with the three food items before the game and then again before half time.

 

Julia has negotiated with a local pizza delivery company to deliver 14-inch cheese pizzas twice each game – 2 hours before the game and right after the opening kickoff.  Each pizza will cost her $4.50 and will include 6 slices.  She estimates it will cost her $0.50 for each hot dog and $1.00 for each barbecue sandwich if she makes the barbecue herself the night before.  She measured a hot dog and found it takes up about 16 in2 of space, whereas a barbecue sandwich takes up about 25 in2.  She plans to sell a piece of pizza for $1.50 and a hot dog for $1.60 each and a barbecue sandwich for $2.25.  She has $1,500 in cash available to purchase and prepare the food items for the first home game; for the remaining five games she will purchase her ingredients with money she has made from the previous game.

 

Julia has talked to some students and vendors who have sold food at previous football games at Tech as well as at other universities.  From this she has discovered that she can expect to sell at least as many slices of pizza as hot dogs and barbecue sandwiches combined.  She also anticipates that she will probably sell at least twice as many hot dogs as barbecue sandwiches.  She believes that she will sell everything she can stock and develop a customer base for the season if she follows these general guidelines for demand.

 

If Julia clears at least $1,000 in profit for each game after paying all her expenses, she believes it will be worth leasing the booth.

 

A.  Formulate a linear programming model for Julia that will help you to advise her if she should lease the booth.  Formulate the model for the first home game.  Explain how you derived the profit function and constraints and show any calculations that allow you to arrive at those equations.

 

B.  Solve the linear programming model using a computer for Julia that will help you advise her if she should lease the booth.  In this solution, determine the number of pizza slices, hot dogs and barbecue sandwiches she should sell at each game.  Also determine the revenues, cost and profit; and do an analysis of how much money she actually will make each game given the expenses of each game.

 

Do an analysis of the profit solution and what impact it has on Julia’s ability to have sufficient funds for the next home game to purchase and prepare the food.  What would you recommend to Julia?

 

C.  If Julia were to borrow some money from a friend before the first game to purchase more ingredients, she feels she can increase her profits.  What amount, if any, would you recommend to Julia to borrow?

 

D.  Food prices have been rising lately.  Assume purchase costs for the food is now $6.00 for each pizza, $0.75 for each hot dog, and $1.25 for each barbecue sandwich.  Repeat the analysis of Part B.  What would you recommend to Julia to do at this point?

 

 

E.  Julia seems to be basing her analysis on the assumptions that everything will go as she plans.  What are some of the uncertain factors in the model that could go wrong and adversely affect Julia’s analysis?  Given these uncertainties and the results in (B), (C), and (D), what do you recommend that Julia do?  Take into consideration her profit margin for each game.

 

Your work will be graded according to the following rubric.

Most married couples would fairly perform points out

/in /by

According to scientific studies Ron Jaworski Jersey , most married couples would fairly perform points out than finding the divorce. The reality is, married partners would rather go an added mile within their marriage straight forward to prevent a divorce. People today could possibly feel that once granted, a divorce will probably be a relief to a number of poor things that happens in marriages.
