Tambin Inc. produces a gasoline additive that, when added to the gas tank of the average automobile, is designed to increase gas mileage by 10%. The companys controller suspects that the year-end dollar balances shown below in the inventory accounts may be incorrect. Units Costs Work in process, December 31 (materials 100% complete; conversion 60% complete) 34,000 $ 69,000 Finished goods, December 31 39,000 $ 122,500 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. A review of the companys inventory and cost records shows the following: Costs Units Materials Conversion Work in process, beginning of year (materials 100% complete; conversion 50% complete) 29,000 $ 31,000 $ 57,000 Started into production 775,000 Costs added during the year $ 759,000 $ 2,090,000 Units completed during the year 770,000 Required: 1. Determine the equivalent units and the costs per equivalent unit for materials and conversion for the year. (Round your "Cost per equivalent unit" answers to 2 decimal places.) 2. Determine the amount of cost that should be assigned to the ending work in process and finished goods inventories. 3. Prepare the necessary correcting journal entry to adjust the work in process and finished goods inventories to the correct balances as of December 31. (Round intermediate calculations to 2 decimal places.)
