The computation follows:
1. Solve first for the variable cost per unit.
Direct materials $ 6.00
<span>Direct labor $ 3.50
</span>
<span>Variable manufacturing overhead $ 1.50
</span>
<span>Sales commissions $ 1.00
</span>
<span>Variable administrative expense $ 0.50
</span>
<span>= $12.50 variable cost per unit
2. Then deduct the selling price to the variable cost per unit, to get the contribution margin.
</span><span>22 - 12.50 = $9.50 CM per unit</span>
Based on the useful life and the appraised age of the house, the effective age is <u>3 years.</u>
