Lehighton Chalk Company manufactures sidewalk chalk, which it sells online by the box at $50 per unit. Lehighton uses an actual costing system, which means that the actual costs of direct material, direct labor, and manufacturing overhead are entered into work-in-process inventory. The actual application rate for manufacturing overhead is computed each year; actual manufacturing overhead is divided by actual production (in units) to compute the application rate. Information for Lehightons first two years of operation is as follows:

	Year 1			Year 2
Sales (in units)		2,500			2,500
Production (in units)		3,000			2,000
