Answer:
a) $96 per unit
b) $224 per unit
c) 70%
Explanation:
We will have to compute variable cost and contribution margin
Sales $2,400,000
7,500 × 320
Less; Variable cost $720,000
Contribution margin $1,680,000
Less : Fixed cost $120,000
Operating income. $1,560,000
a) Variable cost per unit
= Total variable cost ÷ Total number of units
= $720,000 ÷ 7,500 units
= $96 per unit
b) Unit contribution margin
= Selling price per unit - Variable cost per unit
= $320 - $96
= $224
c) Contribution margin ratio
= (Selling price per unit - Variable cost per unit) ÷ Selling price per unit × 100
= ($320 - $96) ÷ $320 × 100
= $224 ÷ 320 × 100
= 70%
