These nutrients come from food A, which costs 18¢ per unit and supplies 2 grams of protein and 4 of fat, and food B with 6 grams of protein and 2 of fat, costing 12¢ per unit. Food B is bought under a long-term contract requiring that at least 2 units of B be used per serving. How much of each food must be bought to produce the minimum cost per serving?
