Zap Rap Inc. is a manufacturer of audio CDs. The company's chief financial officer is trying to verify the accuracy of the December 31 work in process and finished goods inventories prior to closing the books for the year. He strongly suspects that the year-end dollar balances are incorrect, but he believes that all the other data are accurate. The year-end balances shown on Zap Rap's books are as follows: Work in process, December 31 (materials 100% complete; conversion 50% complete) Finished goods, December 31 Units Costs 30,600 57,300 $111,959 $258,153 There were no finished goods inventories at the beginning of the year. The company uses the weighted-average method of process costing. There is only one processing department.
