Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Sales (90 units): $90,000
100 units:
Direct materials= $40,000
Direct labor= $20,000
Variable factory overhead= $2,000
Under the variable costing method, the unitary product cost is calculated using the direct material, direct labor, and variable overhead.
We need to calculate the unitary variable cost:
Unitary variable cost= total variable cost/ number of units
Unitary variable cost= (40,000 + 20,000 + 2,000) / 100= $620 per unit
Now, we can calculate the contribution margin:
Total contribution margin= total sales - total variable cot
Total contribution margin= 90,000 - 90*620= $34,200
