Make-or-Buy Decision
Fremont Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $58 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 39% of direct labor cost. The unit costs to produce comparable carrying cases are expected to be as follows:
| Direct materials | $29 |
| Direct labor | 16 |
| Factory overhead (39% of direct labor) | 6.24 |
| Total cost per unit | $51.24 |
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 13% of the direct labor costs.
a. Prepare a differential analysis dated September 30 to determine whether the company should make (Alternative 1) or buy (Alternative 2) the carrying case. If required, round your answers to two decimal places. If an amount is zero, enter "0". Use a minus sign to indicate a loss.

b. Assuming there were no better alternative uses for the spare capacity, it would to manufacture the carrying cases. Fixed factory overhead is to this decision.
