Stop Light Bikes could sell its bicycles to retailers either assembled or unassembled. The cost of an unassembled bike is as follows.

	Direct materials	$150
	Direct labor	70
	Variable overhead (70% of direct labor)	49
	Fixed overhead (30% of direct labor)	21
	Manufacturing cost per unit	$290

The unassembled bikes are sold to retailers at $400 each. Stop Light currently has unused productive capacity that is expected to continue indefinitely; management has concluded that some of this capacity can be used to assemble the bikes and sell them at $440 each. Assembling the bikes will increase direct materials by $5 per bike, and direct labor by $5 per bike. Additional variable overhead will be incurred at the normal rates, but there will be no additional fixed overhead as a result of assembling the bikes.
