Assignment #3: Julia’s Food Booth
A. Formulate and solve an L.P. model for this case:

X1 = pizza slices
X2 = hot dogs
X3 = B B Q sandwiches

This model is set up for the first home game.
Next, you would maximize Z = $0.75 x1 + 1.05 x2 + 1.35 x3 which is subject to the following: $0.75x1 + 0.45x2 + 0.90x3 <= 1,500 thus leading to:
24x1 + 16x2 + 25x3 <= 55,296 in^2 of even space: thus you have x 1>=*x2 + x3 giving you X2
_____ >= 2.0 so x1, x2, x3 >=0
X3

All of which is displayed in the graph below. (Note: The oven space needed for a slice of pizza is determined by dividing the total space required by the slice of pizza, 14 x 14 = 196 in^2 by 8 or 24 in^2 per slice. The total space available would be the dimensions of the shelf, 36 in. x 48 in. = 1,728 in^2, multiply that by 2, the times before kickoff and halftime, thus the oven will be filled 55,296in^2.

Solution:X1 = 1,250 slices of pizza
X2 = 1,250 hot dogs
X3 = 0 bbq sandwiches
Z = $2,250

Julia’s profit before expenses should be $2,250. The lease is $1,000 per game thus giving a profit of $1,250.00....
