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., 800 units, 60% completed:
	Direct materials (800 x $ 7)	$ 5,600
	Conversion (800 x 60% x $2.9)	1,392
		$ 6,992
From Smelting Department, 19,200 units		$136,320
Direct labor		35,256
Factory overhead		18,984

During September, 800 units in process on September 1 were completed, and of the 19,200 units entering the department, all were completed except 1,800 units that were 20% completed. Charges to Work in ProcessRolling for October were as follows:

From Smelting Department, 22,100 units	$161,330
Direct labor	47,030
Factory overhead	25,324

During October, the units in process at the beginning of the month were completed, and of the 22,100 units entering the department, all were completed except 1,000 units that were 80% 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.
