Plasto Corporation manufactures a variety of plastic products, including a series of molded chairs. The three models of molded chairs, which are all variations of the same design, are Standard (can be stacked), Deluxe (with arms), and Executive (with arms and padding). The company uses batch manufacturing and has an operation-costing system. The production process includes an extrusion operation and subsequent operations to form, trim, and finish the chairs. Plastic sheets are produced by the extrusion operation, some of which are sold directly to other manufacturers. During the forming operation, the remaining plastic sheets are molded into chair seats and the legs are added; the Standard model is sold after this operation. During the trim operation, the arms are added to the Deluxe and Executive models and the chair edges are smoothed. Only the Executive model enters the finish operation where the padding is added. All of the units produced receive the same steps within each operation. The May production run had a total manufacturing cost of $943,600. The units of production and direct-material costs incurred were as follows:

	Units Produced		Extrusion Materials			Form Materials			Trim Materials			Finish Materials
Plastic sheets	4,700		$	61,100
Standard model	6,500			84,500		$	19,500
Deluxe model	3,500			45,500			10,500		$	7,000
Executive model	1,900			24,700			5,700			3,800		$	9,500
Total	16,600		$	215,800		$	35,700		$	10,800		$	9,500

Manufacturing costs applied during the month of May were as follows:

	Extrusion Operation				Form Operation				Trim Operation				Finish Operation
Direct labor		$	126,160			$	53,000			$	32,400			$	19,000
Manufacturing overhead			282,200				101,700				38,340				19,000

1. For each product produced by Plasto Corporation during the month of May, determine the (a) unit cost and (b) total cost. Be sure to account for all costs incurred during the month.

2. Prepare journal entries to record the flow of production costs during May.
