A dietitian in a hospital is to arrange a special diet composed of three basic foods. The diet is to include exactly 440 units of calcium, 360 units of Iron, and 360 units of vitamin A. The number of units per ounce of each special ingredient for each of the foods is indicated in the table. Construct a mathematical model to complete parts (A) through (C) below Use Gauss-Jordan elimination to solve the model and then interpret the solution. Calcium Iron Vitamin A Units per Ounce Food A 20 10 20 ounces of food A and Food B 10 10 30 GTO (B) How is the diet in part (A) affected if food C is not used? Select the correct choice below, and, if necessary, fill in the answer boxes to complete your choice OA. There is still one solution. The diet requires (Type whole numbers) OB. There are multiple solutions. If the diet uses t ounces of food B, it should use OC. There are no solutions. There is no combination of foods that will meet the diet requirements exactly (C) How is the diet in part (A) affected if the vitamin Arequirement is dropped? Select the correct choice below, and, # necessary, it in the answer boxes to complete your choice OA. There is still one solution. The diet requires ounces of food ounces of food Food C 30 30 10 ounces of food B ounces of food A where t is an integer satisfying sts ounces of fo
