Lean Principles

Bright Night, Inc., manufactures light bulbs. Its purchasing policy requires that the purchasing agents place each quarters 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 61,200 pounds of glass per quarter. Bright Night received two glass bids for the third quarter, as follows:

• Central Glass Company: $22.00 per pound of glass. Delivery schedule: 61,200 (680 lbs. x 90 days) pounds at the beginning of July to last for 3 months.
• Ithaca Glass Company: $22.15 per pound of glass. Delivery schedule: 680 pounds per working day (90 days in the quarter).

Considering only inventory financing costs, what is the additional cost per pound of Central Glass Companys bid if the annual cost of money is 8%? (Hint: Determine the average value of glass inventory held for the quarter and multiply by the quarterly interest charge, then divide by the number of pounds.) Round to the nearest cent.
