In a certain hospital, a nutritionist prepares a menu for patients on low-fat diets. The primary ingredients are chicken and rice. The meal must contain enough protein and iron to meet at least the DOH recommended daily allowance (RDA) for each nutrient. The RDA for protein is 60 grams and 30 milligrams. Each 4-ounce serving of chicken contains 60 grams of protein, 15 milligrams of iron; and 6 grams of fat. Each 1-cup serving of rice contains 12 grams of protein, 9 milligrams of iron, and 3 grams of fat. How much chicken and rice should be included in the meal in order to minimize the amount of fat?
