The Brisbane Manufacturing Company produces a single model ofa CD player. Each player is sold for $195 with a resulting contribution margin of $?1. Brisbane's management is considering a change in its quality control system. Currently, Brisbane spends $38,500 a year to inspect the CD players. An average of 2,000 units turn out to be defective 1,600 of them are detected in the inspection process and are repaired for $15. If a defective CD player is not identied 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 :ac-ray machine for $190,000. The machine would last for ve years and would have salvage value at that time of $19,000. Brisbane would also spend $620,000 immediately to train workers to better detect and repair defective units. Annual inspection costs would increase by $23,000. This new control system would reduce the number of defective units to 300 per yea r. 315 of these defective units would be detected and repaired at a cost of $49 per unit. Customers who still received defective players would be given a refund equal to oneandahalf times the purchase price. Questions 1 o 2 [0 points; unlimited tries] 1.
