General overhead	80,000	Number of direct labor hours

Each product's total activity in each of the three areas are as follows:

	Product A	Product B
Number of setups	100	300
Number of parts	40,000	20,000
Number of direct labor hours	8,000	12,000

What is the activity rate for general overhead?

a.$4.00 per direct labor hour

b.$6.67 per direct labor hour

c.$10.00 per direct labor hour
