Corporation has an activity-based costing system with three activity cost poolsProcessing, Supervising, and Other. In the first stage allocations, costs in the two overhead accounts, equipment expense and indirect labor, are allocated to the three activity cost pools based on resource consumption. Data used in the first stage allocations follow:

Overhead costs:
Equipment expense	$73,000
Indirect labor	$1,000

Distribution of Resource Consumption Across Activity Cost Pools:

	Processing	Supervising	Other
Equipment expense	20%	10%	70%
Indirect labor	20%	20%	60%

In the second stage, Processing costs are assigned to products using machine-hours (MHs) and Supervising costs are assigned to products using the number of batches. The costs in the Other activity cost pool are not assigned to products. Activity data for the company's two products follow:

	MHs (Processing)	Batches (Supervising)
Product W3	7,600	100
Product H3	2,400	900
Total	10,000	1,000

Finally, the costs of Processing and Supervising are combined with the following sales and direct cost data to determine product margins.

	Product W3	Product H3
Sales (total)	$159,500	$154,100
Direct materials (total)	$66,300	$55,300
Direct labor (total)	$77,800	$84,100
