A diet calls for 2 units of fat, 3 units of protein, and 5 units of carbohydrate for a meal.

Suppose food 1 has in each cupful: 10 units of fat, 1 unit of protein, and 2 units of carbohydrates.

Suppose food 2 has in each cupful: 1 unit of fat, 5 units of protein, and 4 units of carbohydrates.

Suppose food 3 has in each cupful: 1 units of fat, 2 units of protein, and 6 units of carbohydrates.
