Julia’s Food Booth Strayer University Quantitative Methods MAT 540 December 12‚ 2012 Dr. L. Joseph 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

a) P=PIZZA H=HOTDOGS S=BARBEQUE SANDWHICHES The L.P. for this case is‚ Maximize: P= 0.75P +1.05H +1.35S Subject to: 24.5p +16h +25s ≤ 55296 0.75p + 0.45h+0.90s ≤ 1500 P – h – s ≥ 0 H - 2s ≥ 0 P ‚ h ‚ s ≥ 0 The optimal solution occurs when P=1250 h-1250 s=0 Profit =$2250 Since the booth costs $1000 to lease per game‚ and the oven is $100 per game‚ then Julia’s overall profit is‚ P = 2250 - 1100 = $1150 Hence it is worth leasing the booth. b) The shadow price for

Give a generic definition for a model According to Wilson’s definition a model is the explicit interpretation of one’s understanding of a situation‚ or simply of one’s idea about that situation. It can be expressed in mathematics‚ symbols or words. But it is essentially a description of entities‚ process or attributes and the relationships between them. It may be prescriptive or illustrative‚ but about all‚ it must be useful. Describe the purpose and uses of models There are various use

Linear Programming Concept Paper There are two types of linear programming: 1. Linear Programming- involves no more than 2 variables‚ linear programming problems can be structured to minimize costs as well as maximize profits. Due to the increasing complexity of business organizations‚ the role of the management executive as a decision maker is becoming more and more difficult. Linear programming is a useful technique to solve such problems. The necessary condition is that the data must be
