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, 80% completed:
	Direct materials (800 x $4.6)	$ 3,680
	Conversion (800 x 80% x $1.9)	1,216
		$ 4,896
From Smelting Department, 18,480 units		$86,856
Direct labor		22,503
Factory overhead		12,117

During September, 800 units in process on September 1 were completed, and of the 18,480 units entering the department, all were completed except 1,900 units that were 30% completed. Charges to Work in ProcessRolling for October were as follows:

From Smelting Department, 21,300 units	$104,370
Direct labor	30,070
Factory overhead	16,193

During October, the units in process at the beginning of the month were completed, and of the 21,300 units entering the department, all were completed except 1,000 units that were 40% 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.

2. Provide the same information for October by recording the October transactions in the four-column work in process account. Construct a cost of production report, and present the October computations (a through d) listed in part (1). If an amount box does not require an entry, leave it blank.

3. The cost per equivalent unit for direct materials increased from August to October. The cost per equivalent unit for conversion costs increased from August to October. These changes should be investigated for their underlying causes, and any necessary corrective actions should be taken.
