.	Management is considering using activity-based costing to apply manufacturing overhead cost to products for external financial reports. The activity-based costing system would have the following four activity cost pools:

Activity Cost Pool	Activity Measure	Estimated Overhead Cost
Maintaining parts inventory	Number of part types	$	108,480
Processing purchase orders	Number of purchase orders		212,000
Quality control	Number of tests run		304,120
Machine related	Machine-hours		64,680
		$	689,280

	Expected Activity
Activity Measure	Mono-Relay	Bi-Relay	Total
Number of part types	528	828	1,356
Number of purchase orders	3,228	1,012	4,240
Number of tests run	5,628	9,578	15,206
Machine-hours	1,028	1,128	2,156

Determine the activity rate for each of the four activity cost pools.
