Unitary variable production cost= $78
Step-by-step explanation:
Giving the following information:
Variable costs per unit:
Direct materials $ 18
Direct labor $ 48

The variable costing method incorporates all variable production costs (direct material, direct labor, and variable overhead).
Unitary variable production cost= 18 + 48 + 12
Unitary variable production cost= $78
