Make-or-Buy Decision Fremont Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $40 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 25% of direct labor cost. The unit costs to produce comparable carrying cases are expected to be as follows:
Direct materials $16
Direct labor 20
Factory overhead (25% of direct labor) 5
Total cost per unit $41
If Fremont 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 5% of the direct labor costs.
