Answer:
Incremental cost= $12.05
Explanation:
Giving the following information:
Direct materials $ 6.60
Direct labor $ 3.90
Variable manufacturing overhead $1.55
I will assume that the production level is between the relevant rage, therefore, fixed costs remain constant.
Incremental cost= total variable manufacturing cost
Incremental cost= 6.6 + 3.9 + 1.55
Incremental cost= $12.05
