Eclipse Computer Company has been purchasing carrying cases for its portable computers at a delivered cost of $ 65 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 .............. $ 30
Direct labor ................ 25
Factory overhead (40% of direct labor) ..... 10
Total cost per unit .............. $ 65
If Eclipse 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 15% of the direct labor costs.

b. On the basis of the data presented, would it be advisable to make the carrying cases or to continue buying them? Explain.
