Suppose that it takes 12 units of carbohydrates and 6 units of protein to
satisfy Jacob's minimum weekly requirements. A particular type of meat contains 2
units of carbohydrates and 2 units of protein per pound. A particular cheese contains
3 units of carbohydrates and 1 unit of protein per pound. The meat costs $3.50 per
pound and the cheese costs $5.10 per pound. How many pounds of each are needed
in order to minimize the cost and still meet the minimum requirements? What is the
minimum cost?
