Answer:
$13.55
Explanation:
The contribution margin per unit is computed as;
= Selling price - (Direct materials + Direct labor + Variable manufacturing overhead + Sales commission + Variable administrative expense)
= $28.10 - ($7.50 + $3.85 + $1.55 + $1.05 + $0.60)
= $28.10 - $14.55
= $13.55
Therefore , the contribution margin per unit is $13.55
