Monica [59]

Answer:

$91

Explanation:

Given the following information,

Direct materials per unit = $54

Direct labor per unit = $20

Variable overhead per unit = $6

Fixed overhead for the year = $462,000

For Absorption costing method, it includes all costs associated with production, including fixed and variable cost. The unit product cost is calculated using direct material, direct labor and total unitary manufacturing overhead.

Unitary cost = (Fixed overhead for the year / Units produced) + Direct materials per unit + Direct labor per unit + Variable overhead per unit

Unitary cost = ($462,000 / 42,000) + $54 + $20 + $6

Unitary cost = $11 + $54 + $20 + $6

Unitary cost = $91

Therefore, the product cost per unit is $91
