Work in Process Account Data for Two Months; Cost of Production Reports

Pittsburgh Aluminum Company uses process costing 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:

Line Item Description	Amount
Bal., 400 units, 20% completed:
Direct materials (400 $3.40)	$1,360
Conversion (400 20% $1.40)	112
Total	$1,472
From Smelting Department, 9,520 units	$33,320
Direct labor	8,627
Factory overhead	4,645

During September, 400 units in process on September 1 were completed, and of the 9,520 units entering the department, all were completed except 900 units that were 60% completed. Charges to Work in ProcessRolling for October were as follows:

Line Item Description	Amount
From Smelting Department, 10,900 units	$40,330
Direct labor	11,660
Factory overhead	6,276

During October, the units in process at the beginning of the month were completed, and of the 10,900 units entering the department, all were completed except 500 units that were 90% 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.

3. The cost per equivalent unit for direct materials

decreasedincreased

from August to October. The cost per equivalent unit for conversion costs

decreasedincreased

from August to October. These changes

need notshould

be investigated for their underlying causes, and any necessary corrective actions should be taken.
