Activity-Based Product Costing

Mello Manufacturing Company is a diversified manufacturer that manufactures three products (Alpha, Beta, and Omega) in a continuous production process. Senior management has asked the controller to conduct an activity-based costing study. The controller identified the amount of factory overhead required by the critical activities of the organization as follows:

Activity		Activity Cost Pool
Production			$259,200
Setup			55,000
Materials handling			9,750
Inspection			60,000
Product engineering			123,200
	Total		$507,150

The activity bases identified for each activity are as follows:

Activity	Activity Base
Production	Machine hours
Setup	Number of setups
Materials handling	Number of parts
Inspection	Number of inspection hours
Product engineering	Number of engineering hours

The activity-base usage quantities and units produced for the three products were determined from corporate records and are as follows:

		Machine Hours			Number of Setups			Number of Parts			Number of Inspection Hours			Number of Engineering Hours			Units
Alpha		1,440			75			65			400			125			1,800
Beta		1,080			165			80			300			175			1,350
Omega		720			310			180			500			140			900
	Total	3,240			550			325			1,200			440			4,050

Each product requires 48 minutes per unit of machine time.

Required:

If required, round all per unit amounts to the nearest cent.

1. Determine the activity rate for each activity.
