Activity-Based Product Costing

Roberts Company produces two weed eaters: basic and advanced. The company has four activities: machining, engineering, receiving, and inspection. Information on these activities and their drivers is given below.

		Basic		Advanced		Total
Units produced		90,000		270,000
Prime costs		$6,480,000		$30,240,000		$36,720,000
Machine hours		90,000		450,000		540,000
Engineering hours		400		3,600		4,000
Receiving orders		500		1,500		2,000
Inspection hours		900		1,800		2,700
Overhead costs:
Machining		$5,940,000
Engineering		2,400,000
Receiving		400,000
Inspecting products		513,000

Required:

1. Calculate the four activity rates.

Machining rate	$___ per machine hour
Engineering rate	$ ___per hour
Receiving rate	$ ___per order
Inspecting rate	$__ per hour

2. Calculate the unit costs using activity rates. Round your answers to the nearest cent.

	Unit cost
Basic	$ ___per unit
Advanced	$___ per unit

Calculate the overhead cost per unit. Round your answers to the nearest cent.

	Overhead Cost
Basic	$ ____per unit
Advanced	$____ per unit

3. If consumption ratios instead of activity rates were used to assign costs instead of activity rates, show the cost assignment for the inspection activity.
