Three pounds of material R (costing \($5\) per pound) and 4 pounds of material S (costing \($7\) per pound) are required to make one unit of product T. If management plans to increase the inventory of material R by 500 pounds and reduce the inventory of material S by 800 pounds during a period when 3,000 units of product T are to be produced, what are the budgeted purchase costs of material R and material S?
