Three foods have the following nutritional content per ounce.

a. A diet must consist precisely of 220 units of vitamin A, 180 units of iron, and 340 units of calcium. However, the dietician runs out of Food 1. Use a matrix approach to show that under these conditions the dietary requirements cannot be met.

b. Now suppose that all three foods are available. Use matrices to give two possible ways to meet the iron and calcium requirements with the three foods.
