Suppose the only foods in the world are as follows: After consulting with nutritionists, we decree that a satisfactory diet has at least 2000kcal of energy, 55g of protein, and 800mg of calcium (vitamins and iron are supplied by pills). While some of us would be happy to subsist on 10 servings of pork and beans, we have decided to impose variety by having a limit on the number of servings/day for each of our six foods. Formulate this problem as an LP model. NO need to solve it
