X Company no longer has the space necessary to produce all of its parts. A company has offered to supply one of X Company's parts for $25.45 per unit. This year, production was 15,000 units; next year, production is expected to be 17,600 units. Total production costs for the part this year were:

Materials	$152,100
Direct labor	136,950
Variable overhead	82,800
Fixed overhead	56,700
Total	$428,550

$7,938 of X Company's fixed overhead can be avoided if it buys the part. In addition, if X Company buys the part, it will be able to rent some equipment that will no longer be needed, to a company for $3,500.
