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		110,000		330,000
Prime costs		$7,920,000		$38,940,000		$46,860,000
Machine hours		110,000		550,000		660,000
Engineering hours		400		3,600		4,000
Receiving orders		400		1,200		1,600
Inspection hours		900		1,800		2,700
Overhead costs:
Machining		$9,900,000
Engineering		2,280,000
Receiving		352,000
Inspecting products		351,000

Required:

1. Calculate the four activity rates.

Machining rate	$fill in the blank 1 per machine hour
Engineering rate	$fill in the blank 2 per hour
Receiving rate	$fill in the blank 3 per order
Inspecting rate	$fill in the blank 4 per hour

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

	Unit cost
Basic	$fill in the blank 5 per unit
Advanced	$fill in the blank 6 per unit

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

	Overhead Cost
Basic	$fill in the blank 7 per unit
Advanced	$fill in the blank 8 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.

	Cost assignment
Basic	$fill in the blank 9
Advanced	$fill in the blank 10
