The following table shows the manufacturing cost of each unit is calculated, using activity-based costing, for these manufacturing cost pools.

Cost Pools		Allocation Base		Costing Rate
Materials handling		Number of parts			$3.75	per part
Manufacturing supervision		Hours of machine time			$24.50	per hour
Assembly		Number of parts			$5.55	per part
Machine setup		Each setup			$48.60	per setup
Inspection and testing		Logged hours			$65.00	per hour
Packaging		Logged hours			$35.00	per hour

BSI currently sells the A10 model for $3,250 and the A25 model for $1,835. Manufacturing costs and activity usage for the two products follow:

	A-10			A-25
Direct materials		$143.76			$76.44
Number of parts		131			102
Machine-hours		9.00			6.00
Inspection time		2.00			1.10
Packing time		1.20			0.60
Setups		22			11

Required:

1. Calculate the product cost and product margin for each product.

2. A new competitor has entered the market for lens-polishing equipment with a superior product at significantly lower prices, $2,330 for the A10 model and $1,715 for the A25 model. To try to compete, BSI has made some radical improvements in the design and manufacturing of its two products. The materials costs and activity usage rates have been decreased significantly, as follows:

	A-10			A-25
Direct materials	$	98.65		$	52.45
Number of parts		130			101
Machine-hours		10.0			4.0
Inspection time		2.0			1.00
Packing time		1.00			0.40
Setups		11			11
