Kinnear Plastics manufactures various components for the aircraft and marine industry. Kinnear buys plastic from two vendors: Ta
ppan Corporation and Hill Enterprises. Kinnear chooses the vendor based on price. Once the plastic is received, it is inspected to ensure that it is suitable for production. Plastic that is deemed unsuitable is disposed of. The controller at Kinnear collected the following information on purchases for the past year: Tappan Hill Total purchases (tons) 4,500 7,500 Plastic discarded 135 375 The purchasing manager has just received bids on an order for 170 tons of plastic from both Tappan and Hill. Tappan bid $1,358 and Hill bid $1,349 per ton. Required: 1-a. Assume that the average quality, measured by the amounts discarded from the two companies, will continue as in the past. What is the effective cost per ton for both Tappan and Hill
A=12 120% of a =80% of b 120%a = 80%b 120a/100 = 80b/100 Divide through by 100 120a = 80b Divide through by 80 120a/80 = b But a=12 120x 12/80 = b 18 = b b = 18
