P21-6B ToolTime uses three departments to produce screwdrivers with plastic handles. Forming the handles requires mixing the raw materials, molding, and drying. ToolTime's Drying Department requires no direct materials. Other process costing infor- mation follows: T Units: Beginning work in process (30% complete as to conversion work)...... Transferred in from the Molding Department during the period...... Completed during the period. Ending work in process (20% complete as to conversion work). Costs: Beginning work in process. Transferred in from the Moldling Department during the period.. Conversion costs added during the period... 7,000 units 28.000 units 16,000 units 19,000 units $ 371 4.760 1.947 After the drying process, the screwdrivers are completed by assembling the handles and shanks and packaging for shipment to retail outlets. The cost transferred in to the assembling phase is the cost of the plastic handles transferred out of the Drying Department. ToolTime uses FIFO process costing. Required 1. Draw a time line of the Drying Department's process, similar to the one in Exhibit 21-11. 2. Use the time line to compute the number of equivalent units of work performed by the Drying Department during the period, the cost per equivalent unit, and the total costs to account for. 3. Assign total cost to

(a) units completed and transferred to the assembly operation, and

(b) units in the Drying Department's ending work in process inventory.
