A dietitian in a hospital is to arrange a special diet using three foods, L, M, and N. Each ounce of food L contains 40
units of calcium, 20 units of iron, 10 units of vitamin A, and 20 units of cholesterol. Each ounce of food M contains 20
units of calcium, 20 units of iron, 15 units of vitamin A, and 20 units of cholesterol. Each ounce of food N contains 20
units of calcium, 20 units of iron, 10 units of vitamin A, and 18 units of cholesterol.

If the minimum daily requirements are 640 units of calcium, 440 units of iron, and 240 units of vitamin A, how many ounces of each food should be used to meet the minimum requirements and at the same time minimize the cholesterol intake?
