Bright Night, Inc., manufactures light bulbs. Its purchasing policy requires that the purchasing agents place each quarter’s purchasing requirements out for bid. This is because the Purchasing Department is evaluated solely by its ability to get the lowest purchase prices. The lowest bidder receives the order for the next quarter (90 working days). 

To make its bulb products, Bright Night requires 36,000 pounds of glass per quarter. Bright Night received two glass bids for the third quarter, as follows:

• Central Glass Company: $30.00 per pound of glass. Delivery schedule: 36,000 (400 lbs. × 90 days) pounds at the beginning of July to last for 3 months.

• Ithaca Glass Company: $30.20 per pound of glass. Delivery schedule: 400 pounds per working day (90 days in the quarter).

Bright Night accepted Central Glass Company’s bid because it was the low-cost bid.
