3 Consider the diet problem discussed in Section 3.4. Use the LINDO output in Figure 8 to answer the following questions. a If a Brownie costs 30, then what would be the new optimal solution to the problem? b If a bottle of cola cost 35, then what would be the new optimal solution to the problem? If at least 8 oz of chocolate were required, then what would be the cost of the optimal diet? d If at least 600 calories were required, then what would be the cost of the optimal diet? e If at least 9 oz of sugar were required, then what would be the cost of the optimal diet? My diet requires that all the food I eat come from one of the four basic food groups (chocolate cake, ice cream, soda, and cheesecake). At present, the following four foods are available for consumption: brownies, chocolate ice cream, cola, and pineapple cheese- cake. Each brownie costs 50, each scoop of chocolate ice cream costs 20, each bottle of cola costs 30$, and each piece of pineapple cheesecake costs 80. Each day, I must in- gest at least 500 calories, 6 oz of chocolate, 10 oz of sugar, and 8 oz of fat. The nutri- tional content per unit of each food is shown in Table 2. Formulate a linear programming model that can be used to satisfy my daily nutritional requirements at minimum cost.
