Narayan Corporation has an activity-based costing system with three activity cost pools - Machining, Setting Up, and Other. The company's overhead costs, which consist of equipment depreciation and indirect labor, have been allocated to the cost pools already and are provided in this table:

	Machining	Setting Up	Other	Total
Equipment depreciation	$27,200	$6,800	$34,000	$68,000
Indirect Labor	$2,500	$1,000	$1,5000	$5,000
Total	$29,700	$7,800	$35,500	$73,000

Costs in the Machining cost pool are assigned to products based on a machine-hours (MHs) and costs in the Setting up cost pool are assigned to products based on the number of batches. Costs in the Other cost pool are not assigned to products. Data concerning the two products and the company's costs appear below:

	MHs	Batches
Product Z9	4,400	400
Product Q2	5,600	1,600
Total	10,000	2,000

	Product Z9	Product Q2
Sales (total)	$137,900	$173,300
Direct materials (total)	$59,700	$43,400
Direct labor (total)	$57,500	$96,000
