9 cost April 10 Assignment Bookworm, Inc., has two departments: printing and binding. Each department has one direct-cost category (direct materials) and one indirect-cost category (conversion costs). This problem focuses on the binding department. Books that have undergone the printing process are immediately transferred the binding department. Direct material is added when the binding process is 80% complete. Conversion costs are added evenly during binding operations. When those operations are done, the books are immediately transferred to Finished Goods. Bookworm, Inc.,. The following is a summary of the April 2012 operations of the binding department: Physical Transferred- Direct Conversion Units In Materials Costs (books) Costs 1,050 $ 32,550 $0 $13,650 Beginning work in process 100% 0% 50% Degree of completion, beginning work in process 2,400 Transferred in during April 2012 2,700 Completed and transferred out during April 750 Ending work in process (April 30) 100% 0% 70% Degree of completion, ending work in process $129,600 $23,490 $70,200 Total costs added during April Transferred-in costs, FIFO method.. Suppose that Bookworm, Inc., uses the FIFO method. r the FIFO method are that total transferred-in costs of beginning work in process on April 1 are $36,750 (instead of $32,550) and that total transferred- in costs added during April are $124,800 (instead of $129,600). 1. Using the FIFO process-costing method, 2. If you did Problem 17-38, explain any difference between the cost of work completed and transferred out and the cost of ending work in process in the binding department under the weighted average method and the FIFO method
