1. Make-or-Buy Decision

   Companion Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $62 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 40% of direct labor cost. The fully absorbed unit costs to produce comparable carrying cases are expected to be as follows:

   Direct materials	$26
   Direct labor	16
   Factory overhead (40% of direct labor)	6.4
   Total cost per unit	$48.4

   If Companion 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 14% of the direct labor costs.
