Weatherly Lumber Company processes wood pulp for manufacturing various paper products. The company employs a process costing system for its manufacturing operations. All direct materials are added at the beginning of the process, and conversion costs are incurred uniformly throughout the process. This is the company’s production schedule for May:

			Percentage Completed
		Tons of Pulp	Materials	Conversion
Work-In-Process Inventory, May 1		4,000	100%	50%
Started during May		12,000
Units to account for		16,000
Units from beginning Work-In-Process, which were completed and transferred out during May		4,000
Started and completed during May		7,200
Work-In-Process Inventory, May 31		4,800
Total units accounted for		16,000

The following cost data are available:

Work-in-Process Inventory, May 1
Direct materials	$61,280
Conversion	7,256
Costs incurred during May
