The Brisbane Manufacturing Company produces a single model of a CD player. Each player is sold for $180 with a resulting contribution margin of $72.

Brisbane's management is considering a change in its quality control system. Currently, Brisbane spends $40,000 a year to inspect the CD players. An average of 2,200 units turn out to be defective: 1,760 of them are detected in the inspection process and are repaired for $85. 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 $200,000. The machine would last for four years and would have salvage value at that time of $20,000. Brisbane would also spend $470,000 immediately to train workers to better detect and repair defective units. Annual inspection costs would increase by $25,000. Brisbane expects this new control system to reduce the number of defective units to 380 per year. 310 of these defective units would be detected and repaired at a cost of only $49 per unit. Customers who still receive defective players will be given a refund equal to 120% of the purchase price.
