Problem 8-51 Operation Costing: Work-in-Process Inventory (LO 8-8) Washington, Inc., makes three models of motorized carts for vacation resorts, X-10, X-20, and X-40. Washington manufactures the carts in two assembly departments: Department A and Department B. All three models are processed initially in Department A, where all material is assembled.

After processing in Department A, the X-20 and X-40 models are transferred to Department B for final assembly, and then transferred to finished goods. There were no beginning work-in-process inventories on April 1. Data for April are shown in the following table.
