X Company is considering buying a part next year that they currently make. This year's production costs for 3,500 units were as follows:

		Per-Unit	Total
Direct materials		$3.11	$10,885
Direct labor		3.34	11,690
Variable overhead		2.60	9,100
Fixed overhead		3.90	13,650
Total		$12.95	$45,325

A company has offered to supply this part to X Company for $12.22 per unit. If X Company accepts the offer, it will still incur fixed costs of $7,508, but it will be able to lease the resources that will become available from not making the part for $2,100. At what production level would X Company be indifferent between making and buying the part next year?
