Problem 5: Process Costing (17 points) The Assembly Department uses a process cost accounting system and a weighted-average cost flow assumption. The department adds materials at the beginning of the process and incurs conversion costs uniformly throughout the process. The units are complete and ready for sale after the process. During July, $190,000 of materials costs and $133,000 in conversion costs were charged to the department. The beginning work in process inventory was $108,000 on July 1, comprised of $80,000 of materials costs and $28,000 of conversion costs. Other data for the month of July are as follows: 25,000 units 90,000 units 10,000 units (40% complete) Beginning work in process inventory, 7/1 Units completed and transferred out Ending work in process inventory, 7/31 (20% complete) Instructions Answer the following questions and show computations to support your answers. 1. What are the equivalent units of production for materials and for conversion costs for the month of July? 2. Compute the unit costs for materials and for conversion costs
