A factory producing pills has to develop a new type of multivitamin using two types of powde powder A and powder B. Each gram of powder A contains 16 units of calcium, 2 units of iron of magnesium and 6 units of vitamin A. Each gram of the same quantity of powder B contain of calcium, 4 units of iron, 13 units of magnesium and 1 unit of vitamin A. Each pill produced factory requires at most 140 units of calcium, at least 360 units of iron and at least 200 units vitamin A. Each gram of powder A costs R25 and each gram of powder B costs R17. How ma of each type of powder should be used to minimize the cost of producing each pill? Let x be the number of grams of powder A used in each pill. Let y be the number of grams of powder B used in each pill. be:
