X Company is considering buying a part next year that they currently make. This year's production costs for 3,400 units were as follows:

		Per-Unit	Total
Direct materials		$2.84	$9,656
Direct labor		3.21	10,914
Variable overhead		4.40	14,960
Fixed overhead		3.40	11,560
Total		$13.85	$47,090

A company has offered to supply this part to X Company for $13.70 per unit. If X Company accepts the offer, it will still incur fixed costs of $6,127, but it will be able to lease the resources that will become available from not making the part for $2,600. At what production level would X Company be indifferent between making and buying the part next year?
