Omnisport manufactures and sells sports equipment. It currently produces and sells 5,000 pairs (units) of in-line skates each year, operating at maximum machine capacity. Omnisports market research has revealed that it could sell 8,000 pairs of in-line skates annually. Calcott Inc., a nearby supplier, has offered to supply up to 6,000 pairs of in-line skates at a price of $75 per pair. However, Jack Petrone, Omnisports product manager, has noticed the current snowboarding craze and believes that Omnisport could sell up to 12,000 pairs (units) of snowboard bindings annually. Omnisports management accountant summarizes the available data: Manufactured Inline Skates (pair)		Snowboard Bindings (pair)		Purchased Inline Skates (pair)
Selling Price	$98		$60		$98
Cost per unit
Purchase cost	-		-		$75
Direct material	20		20		-
Variable machine operating cost ($16 per machine hour)	24		8		-
Variable and fixed manufacturing overhead (allocation base: machine hours)	18		6		-
Variable marketing and administrative cost	9		8		4

• Fixed manufacturing overhead costs of $30,000 are not affected by the product-mix decision.
• Fixed manufacturing overhead costs are allocated to products based on a machine-hour rate, which is calculated by dividing total fixed manufacturing overhead costs of $30,000 by machine-hour capacity.
• Fixed marketing and administrative costs of $60,000 are not affected by the product-mix decision.

Question:

How many machine-hours does each pair of manufactured in-line skates need? Each pair of snowboard bindings? If Omnisport produces only 12,000 pairs of snowboard bindings, what would be the cost of unused manufacturing capacity?
