The Brisbane Manufacturing Company gives a single model of a CD player. Each player is sold for $202 with a resulting contribution margin of $70.

Brisbane's management is considering a change in its quality control system. presently, Brisbane spends $41,500 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 the rest are shipped to customers. If a defective CD player is identified in the inspection process, it costs $75 to fix it. If a defective CD player is not identified in the inspection process, the customer who receives it is provided a full refund of the purchase price. Competitors are expected to enhance their quality control systems in the future, so if Brisbane does not improve its system, sales volume is expected to fall by 450 CD players a year for next four years. In other words, it will fall by 450 units in the first year, 900 units in the second year, etc..
The proposed quality control system has 2 elements. First, Brisbane would spend $780,000 instantly to train workers to better detect and correct defective units. Second, an x-ray machine could be purchased to improve detection. This machine could cost $310,000, last for four years, and have salvage value at that time of $22,000. Annual inspection costs should increase by $23,000. Both of these elements should reduce the number of defective units to 350 per year. 285 of these defective units should be detected and repaired at a cost of $40 per unit. Customers who received defective players would be specified a refund equal to one-and-a-fourth times the purchase price.
