Greife Corporation's activity-based costing system has three activity cost pools--Machining, Setting Up, and Other. The company's overhead costs have already been allocated to these cost pools as follows:

Machining	$	34,122
Setting Up	$	73,005
Other	$	24,000

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. The following table shows the machine-hours and number of batches associated with each of the company's two products:

	MHs	Batches
Product K0	2,190	1,320
Product W9	8,150	230
Total	10,340	1,550
