The Assembly Department uses a process cost accounting system and the weighted-average cost flow assumption. The department adds materials at the beginning of the process and incurs conversion costs uniformly throughout the process. During July, $167,200 of materials costs and $120,648 in conversion costs were charged to the department. The beginning work in process inventory was $55.440 on July 1, comprised of $44,000 of materials costs and $11,440 of conversion costs. Other data for the month of July are as follows: Beginning work in process inventory, 7/1 22,000 units (40% complete as to conversion costs) 61,600 units Units completed and transferred out Ending work in process inventory, 7/31 26,400 units (30% complete as to conversion costs) Answer the following questions.
