Diamond Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $111 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 50% of direct labor cost. The fully absorbed unit costs to produce comparable carrying cases are expected to be as follows:

Direct materials	$55
Direct labor	40
Factory overhead (50% of direct labor)	20
Total cost per unit	$115

If Diamond Computer Company manufactures the carrying cases, fixed factory overhead costs will not increase and variable factory overhead costs associated with the cases are expected to be 10% of the direct labor costs.
