Answer:
Contribution margin ratio
= Contribution per unit
Selling price
= Selling price - Unit variable cost
Selling price
0.30 = $58 - Unit variable cost
$58
0.30($58) = $58 - Unit variable cost
$17.40 = $58 - Unit variable cost
Unit variable cost = $58 - $17.40
Unit variable cost = $40.60
The correct answer is B
Explanation:
In this case, we need to apply the formula for contribution margin ratio. Contribution margin ratio is the ratio of contribution per unit to selling price. Contribution per unit equals selling price minus variable cost per shirt. Contribution margin ratio and selling price were given with the exception of variable cost per shirt. Thus, variable cost per shirt is made the subject of the formula.
