Musich 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 the table below.

	Activity Cost Pools
	Machining		Setting Up		Other		Total
Equipment depreciation	$	8,400	$	46,200	$	22,800	$	77,400
Indirect labor		3,000		2,400		3,600		9,000
Total	$	11,400	$	48,600	$	26,400	$	86,400

Costs in the Machining cost pool are assigned to products based on 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 Z3	5,500	500
Product T1	5,700	1,100
Total	11,200	1,600

	Product Z3		Product T1

Direct materials (total)	$	81,500	$	96,600
Direct labor (total)	$	109,000	$	102,700
