The Brisbane Manufacturing Company produces a single model of a CD player. Each player is sold for $205 with a resulting contribution margin of $73.

Brisbane's management is considering a change in its quality control system. Currently, Brisbane spends $41,000 a year to inspect the CD players. An average of 1,800 units turn out to be defective - 1,260 of them are detected in the inspection process and are repaired for $75. If a defective CD player is not identified in the inspection process, the customer who receives it is given a full refund of the purchase price.

The proposed quality control system involves the purchase of an x-ray machine for $180,000. The machine would last for four years and would have salvage value at that time of $21,000. Brisbane would also spend $590,000 immediately to train workers to better detect and repair defective units. Annual inspection costs would increase by $25,000. This new control system would reduce the number of defective units to 350 per year. 280 of these defective units would be detected and repaired at a cost of $48 per unit. Customers who still received defective players would be given a refund equal to one-and-a-fourth times the purchase price.
