APCO Company manufactures various lines of bicycles. Because of the high volume of each line, the company employs a process costing system using the weighted-average method. Bicycle parts are manufactured in the molding department and then are consolidated into a single bike unit in the molding department and transferred to the assembly department where they are assembled. After assembly, the bicycle is sent to the packing department. Annual cost and production figures for the assembly department are presented in the schedules below.

Defective bicycles are identified at the inspection point when the assembly labor process is 70% complete; all assembly materials have been added at this point. The normal rejection rate for defective bicycles is 5% of the bicycles reaching the inspection point. Any defective bicycles above the 5% quota are considered to be abnormal. All defective bikes are removed from the production process and destroyed.
