Waterway Industries works hard to keep pace with demand for its modern chandelier. To get it out the door, Waterway first machines raw materials into key component parts. Next, the component parts are assembled. These two processing departments work together, coordinating the output from the machining process into the assembly process. All DM resources are added at the beginning of the machining process, while conversion costs are added evenly throughout the process. For May, the following information was available for the machining process. Units in beginning WIP Inventory Beginning WIP Inventory degree of completion Costs in beginning WIP Inventory New units started Costs added to WIP Inventory this period Units completed Units in ending WIP Inventory Ending WIP Inventory degree of completion a) Total cost of units completed Units Cost of units in ending WIP Inventory $ 500 7,800 7,100 1,200 DM $31.800 $366,600 Conversion Costs 70% $17.730 $209,670 Determine the total cost of units completed and the cost of units in ending WIP Inventory-Machining in May by completing Steps 1-5 of the template, assuming Waterway Industries uses the FIFO method of process costing. 40%
