Question

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., 1,200 units, 20% completed:
	Direct materials (1,200 x $4.1)	$ 4,920
	Conversion (1,200 x 20% x $1.7)	408
		$ 5,328
From Smelting Department, 27,120 units		$113,904
Direct labor		31,871
Factory overhead		17,161

During September, 1,200 units in process on September 1 were completed, and of the 27,120 units entering the department, all were completed except 2,100 units that were 60% completed. Charges to Work in Process—Rolling for October were as follows:

From Smelting Department, 31,200 units	$137,280
Direct labor	40,410
Factory overhead	21,758

During October, the units in process at the beginning of the month were completed, and of the 31,200 units entering the department, all were completed except 1,600 units that were 90% 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.
