Zee-Drive Ltd. is a computer manufacturer. One of the items they make is monitors. Zee-Drive has the opportunity to purchase 16,400 monitors from an outside supplier for $205 per unit. One of the company's cost-accounting interns prepared the following schedule of Zee-Drive's cost to produce 16,400 monitors:

	Total cost of producing 16,400 monitors		Unit cost
Direct materials	$	1,918,800	$	117
Direct labor		1,066,000		65
Variable factory overhead		590,400		36
Fixed manufacturing overhead		492,000		30
Fixed non-manufacturing overhead		672,400		41
	$	4,739,600	$	289

You are asked to look over the intern's estimate before the information is shared with members of management who will decide to continue to make the monitors or buy them. The company's controller believes that the estimate may be incorrect because it includes costs that are not relevant. If Zee-Drive buys the monitors, the direct labor force currently employed in producing the monitors will be terminated and there would be no termination costs incurred. There are no materials on hand and no commitments to suppliers to purchase materials, so all materials would need to be purchased to make the monitors. Variable overheads are avoidable if monitors are bought. Fixed manufacturing overhead costs would be reduced by $56,700, but non-manufacturing costs would remain the same if monitors are bought.
