d. Formulate this same model e. Use the graphical method by hand to solve this model. 2.23. Dwight is an elementary school teacher who also raises pigs for supplemental income. He is trying to decide what to feed his pigs. He is considering using a combination of pig feeds available from local suppliers. He would like to feed the pigs at minimum cost while also making sure each pig receives an adequate supply of calories and vitamins. The cost, calorie content, and vitamin content of each feed is given in the table below. Contents Calories (per pound) Vitamins (per pound) Cost (per pound) Feed Type A 800 140 units $0.40 Feed Type B 1,000 70 units $0.80 Each pig requires at least 8,000 calories per day and at least 700 units of vitamins. A further constraint is that no more than 1/3 of the diet (by weight) can consist of Feed Type A, since it contains an ingredient that is toxic if consumed in too large a quantity
