Introduction

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 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.

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 this case.

Decision Variables

Representing “x1” as pizza slices, “x2” as hot dogs, and “x3” as barbeque sandwich

The Objective Function

The objective is to maximize total profit. Profit is calculated for each variable by subtracting cost from the selling price.

For Pizza slice, Cost/slice=\$6/8=\$0.75

Products |Costs |Sell Prices |Profits | |Pizza |0.75 |1.50 |0.75 | |Hot dog |0.45 |1.50 |1.05 | |Barbeque Sandwich |0.90 |2.25 |1.35 | |

The model is for the first home game,

Maximize Z = \$0.75x1 + \$1.05x2 + \$1.35x3

Where

Z = Total profit

\$0.75x1 = profit from pizza

\$1.05x2 = profit from hot dog

\$1.35x3 = profit from barbeque sandwich

Model Constraints

1. Budget \$0.75x1 + \$0.45x2 + \$0.90x3 = 2.0
5. More than or equal zero X1, X2, X3 >= 0

Graphical Solution of a Maximization Model Maximize Z = \$0.75x1 + \$1.05x2 + \$1.35x3 Subject to: \$0.75x1 + \$0.45x2 + \$0.90x3 = 2.0
X1, X2, X3 >= 0
Solution

...Week 8 Assignment 1 Keila Stinson Strayer University MAT 540 Dr. Negash Begashaw March 2, 2015 In the case study regarding Julia’s food booth a solution needs to be determined as to if investing in a booth to sell food during Tech football games is a sound investment. Julia is considering leasing a booth to sell food outside of Tech stadium at home football games to generate revenue in order to finance her final year at the school. After all of her expenses are paid Julia wants to bring in a profit of \$ 1,000 per game. If she can accomplish this then she feels that it will be worth the money to invest in a booth. The fixed cost associated with leasing the booth would include \$1,000 per game for booth rental and \$600 to lease a warming oven for the six home football games. Julia’s has \$1,500 available cash, which she will use to purchase and prepare the food for the first game. For the remaining home games she plans on using funds generated from the previous game to purchase her ingredients. In order to help Julia determine if she should lease a booth a linear programming model should be formulated and solved. The first step in setting up the model is to determine the variables. The variables for this case include: x1 =Pizza, x2 = Hotdogs, and x3= BBQ sandwiches. These variables are the three food choices Julia wishes to sell at her booth. Julia’s objective function in this case is to maximize profit (maximize Z). Julia’s objective function in this case equates...

...Julia’s Food Booth Kenneth W. Dayton Strayer University 11/25/2011 Math 540 Quantitative Reasoning Julia Robertson is a senior at Tech University and wants to find a way to make extra money to finance her final year at school. She is considering leasing a food booth outside the Tech stadium during home football games. Julia knows the games sell out and the crowd eats a lot of food. Julia has spoken with Ken a consultant and has agreed to investigate her leasing a food booth. Ken will look at the following items to determine if it is a good decision. The first item is creating an L.P. model (linear progression) to help understand the constraints and how to maximize her profit. Julia was asking if she should borrow money from a friend so this will also be evaluated. Julia wants to hire friend to help her with the booth and she is uncertain about the impact of the model. By looking at the L.P. model Ken can determine her best course of action and if she should lease the booth. The first step is to create the L.P. model to determine an objective function. The objective function ken determines to use is Max Z= .75p+1.05h+1.35b which can be done by looking at the information available such as items being sold, how much those items cost Julia to buy, how much she plans to sell each item for, looking at how one item can sell as much as or more than another item. Julia wants to sell Pizza, Hot Dogs, and Bar-B-Q sandwiches. Julia is going to have a Pizza company deliver a 14......

...Julia’s Food Booth NAME Strayer University MAT 540 LECTURER DATE Julia’s Food Booth Formulate and solve an L.P. model for this case. Julia Robertson is trying to advance her education and financing her education, to do so she started a food booth outside the Tech stadium selling Slices of cheese pizza, hot dogs, and barbecue sandwiches. This covers the items X1, X2, and X3 respectively. The costs of these items are \$4.50, \$0.50 and \$1.00 respectively. As one knows the objective is to maximize Julia Robertson’s profit. The method of doing this is by evaluating subtracted costs from the selling price. Things to consider are constraints and the cost of everything involved. Being that cost always seems the most important this paper will start there. Profit on pizza slice = \$1.50 - \$0.75 = \$ 0.75 Profit on hot dog = \$1.50 – 0.45 = \$1.05 Profit on sandwich = \$2.25 - \$0.90 = \$1.35 The overall profit would be the following: Z=0.75 X1+ 1.05 X2 + 1.35 X3 Constraints: Budget Constraints would go as follows: 0.75X1 + 0.45X2 + 0.90X3 <=\$1500 Space Constraints: Space available = 3 x 4 x 16 = 192 sq. feet = 192 x 12 x 12 =27648 sq. inches The oven will be refilled during half time. Thus total space available = 27648 x 2 = 55296 Space required for pizza = 14 x 14 = 196 sq. inches Space required for pizza slice = 196/ 8 = 24.5 sq. inches Total Oven Space required: 24.5 X1 + 16 X2 + 25 X3 Constraint: 24.5 X1 + 16 X2 + 25 X3 ≤ 55296 sq.

...Running head: JULIA’S FOOD BOOTH 1 Case Study Julia’s Food Booth Susan Dawson Strayer University JULIA’S FOOD BOOTH 2 Case Study: Julia’s Food Booth In this case study, we are asked to determine if Julia Robertson, a senior at Tech, should finance her final year at Tech in part by opening a food booth outside the stadium at home football games. We are also asked to determine if she should borrow more money, hire preparation assistance and what could go wrong. Julia is considering opening a food booth outside the stadium at six (6) home football games at a booth rental charge of \$1,000.00 per game. Due to existing regulations, she knows she can only sell food or drinks, not both. She has determined the most popular food items are slices of pizza, hot dogs and barbecue sandwiches and that most food sales occur during the hour before the game and during half-time. She has been able to secure a deal with a pizza delivery company to deliver 14” pizzas, 8 slices each, for \$6.00 and, because of demand, she must prepare the other food in advance and keep it warm ahead of sales. She found that she can rent a warming oven with 16 shelves, each 3’ x 4’, for a seasonal cost of \$600.00 or \$100.00 per game. Julia has \$1,500.00 available to purchase food for the first game.
