Class Diet
Problem from http://www.mcs.vuw.ac.nz/courses/OPRE251/2006T1/Labs/lab09.pdf
My diet requires that all the food I eat come from one of the four .basic food groups. (chocolate cake, ice cream, soft drink, and cheesecake). Each (large) slice of chocolate cake costs 50c, each scoop of chocolate ice cream costs 20c, each bottle of cola costs 30c, and each piece of pineapple cheesecake costs 80c.
Each day, I must ingest at least 500 calories, 6 oz of chocolate, 10 oz of sugar, and 8 oz of fat. The nutritional content per unit of each food is shown in the table below.
Formulate a linear programming model that can be used to satisfy my daily nutritional requirement at minimum cost.
Type of Calories Chocolate Sugar Fat Food (ounces) (ounces) (ounces) Chocolate Cake (1 slice) 400 3 2 2 Chocolate ice cream (1 scoop) 200 2 2 4 Cola (1 bottle) 150 0 4 1 Pineapple cheesecake (1 piece) 500 0 4 5
