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 ProcessRolling on September 1 and debits to the account during September were as follows: Bal., 2,600 units, completed: Direct materials (2,600 x $15.50) $40,300 Conversion (2,600 x x $8.50) 5,525 $45,825 From Smelting Department, 28,900 units $462,400 Direct labor 158,920 Factory overhead 101,402 During September, 2,600 units in process on September 1 were completed, and of the 28,900 units entering the department, all were completed except 2,900 units that were 4/5 completed. Charges to Work in ProcessRolling for October were as follows: From Smelting Department, 31,000 units $511,500 Direct labor 162,850 Factory overhead 104,494 During October, the units in process at the beginning of the month were completed, and of the 31,000 units entering the department, all were completed except 2,000 units that were 2/5 completed. Required: 1. Enter the balance as of September 1 in a four-column account for Work in ProcessRolling. 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. ACCOUNT Work in Process-Rolling Department ACCOUNT NO. BALANCE DATE ITEM POST. REF.
