Answer:
d. $31.75
Step-by-step explanation:
Computation for the total production cost per unit
Direct labor $8.50 per unit
Direct material $9.00 per unit
Variable overhead $6.75 per unit
Fixed overhead ($60,000/8,000 units) $7.50 per unit
Total production cost per unit $31.75
($8.50 + $6.75 + $9.00 + $7.50)
Therefore the total production cost per unit under variable costing if 20,000 units had been produced will be $31.75
