Your diet must provide minimum amounts of the following items: calories, calcium, vitamin A, riboflavin, and ascorbic acid. Your daily requirement for these items (in the above order) may be determined by reading off the numerical values corresponding to the first five letters of your name on Table 1. The following are the units used: 10 calories, 10 grams, 103 international units, milligrams, and 10 milligrams. Your choice of foods is somewhat limited because you find it financially advantageous to trade at a discount store that has little imagination. You can buy: (1) wheat flour (enriched), (2) evaporated milk, (3) cheddar cheese, (4) beef liver, (5) cabbage, (6) spinach, (7) sweet potatoes, (8) lima beans (dried). The nutritional values per dollar spent have been tabulated by Dantzig in Table 2. In addition, the store features a greyish powder, (9) Product X, sold in bulk, whose nutritional values per unit cost are also given in Table 1. The units (same order of items as before) are 10 calories/dollar, 10 grams/dollar, 10 international units/dollar, 10 milligrams/dollar, milligrams/dollar. Your doctor has coded your diet requirements and the nutritional properties of Product X under the first five letters of your name in Table 1.

How much would you be willing to pay for pure vitamin A? pure riboflavin? f) If the wheat flour were enriched by 10 units of vitamin A without additional cost, would this change your diet? g) A new food has come out (called GLUNK) having nutritional values per dollar of 83, 17, 25, 93, 07 (values are in the same order as for Product X). Would you want to include the new food in your diet?
