Work in Process Account Data for Two Months; Cost of Production Reports
Pittsburgh Aluminum Company uses a process cost system to record the costs of manufacturing rolled aluminum, which consists of the smelting and rolling processes. Materials are entered from smelting at the beginning of the rolling process. The inventory of Work in Process—Rolling on September 1 and debits to the account during September were as follows:
Bal., 400 units, 30% completed:
Direct materials (400 x $3.1)$ 1,240
Conversion (400 x 30% x $1.3)156
$ 1,396
From Smelting Department, 9,320 units$29,824
Direct labor8,672
Factory overhead4,670
During September, 400 units in process on September 1 were completed, and of the 9,320 units entering the department, all were completed except 700 units that were 90% completed. Charges to Work in Process—Rolling for October were as follows:
From Smelting Department, 10,700 units$36,380
Direct labor10,720
Factory overhead5,765
During October, the units in process at the beginning of the month were completed, and of the 10,700 units entering the department, all were completed except 500 units that were 60% completed.
Required:
1. Enter the balance as of September 1 in a four-column account for Work in Process—Rolling. Record the debits and the credits in the account for September. Construct a cost of production report and present computations for determining (a) equivalent units of production for materials and conversion, (b) costs per equivalent unit, (c) cost of goods finished, differentiating between units started in the prior period and units started and finished in September, and (d) work in process inventory. If an amount box does not require an entry, leave it blank.
