The Assembly Department uses a process cost accounting system and the weighted-average cost ow assumption. The department adds materials at the beginning of the process and incurs conversion costs uniformly throughout the process. During July, $186,200 of materials costs and $134,358 in conversion costs were charged to the department. The beginning work in process inventory was $61,740 on July 1, comprised of $49,000 of materials costs and $12,740 of conversion costs. Other data for the month of July are as follows: Beginning work in process inventory, 7/1 24,500 units {40% complete as to conversion costs) Units completed and transferred out 68,600 units Ending work in process inventory, 7/31 29,400 units {30% complete as to conversion costs) Answer the following questions. Answer the following questions and show computations to support your answers. 1. How many physical units have to be accounted for in July? 2. What are the equivalent units of production for materials and for conversion costs for the month of July? 3. What is the total cost assigned to the units that were transferred out of the process in July? What is the total cost of the July 31 inventory? - 68, 600
