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		$2.40	$8,160
Direct labor		3.54	12,036
Variable overhead		3.50	11,900
Fixed overhead		4.00	13,600
Total		$13.44	$45,696

A company has offered to supply this part to X Company for $12.89 per unit. If X Company accepts the offer, it will still incur fixed costs of $6,256, but it will be able to lease the resources that will become available from not making the part for $2,800. At what production level would X Company be indifferent between making and buying the part next year?
