An animal food must provide 60 units of vitamins and 65 calories per serving. One gram of soybean meal provides 2.5 units of vitamins and 5 calories. One gram of meat byproducts provides 4.5 units of vitamins and 3 calories. One gram of grain provides 5 units of vitamins and 10 calories. A gram of soybean meal costs 8¢​, a gram of meat byproducts 9¢​, and a gram of grain 10¢. ​
(a) What mixture of these three ingredients will provide the required vitamins and calories at minimum​ cost?
