Kinnear Plastics manufactures various components for the aircraft and marine industry. Kinnear buys plastic from two vendors: Tappan 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)	2,200	4,100
Plastic discarded	110	410

The purchasing manager has just received bids on an order for 150 tons of plastic from both Tappan and Hill. Tappan bid $741 and Hill bid $720 per ton.
