Answer and Explanation:
The computation is shown below:
The Selling price per unit = $225,000 ÷ 7500 = $30
ANd,
Variable cost per unit = $135,000 ÷ 7500 = $18
a) Breakeven point = Fixed cost ÷ Contribution margin per unit
= $48,000 ÷ ($30 - $18)
= 4000 units
b) Breakeven dollars = Breakeven point × selling price per unit
= 4000 × 30
= $120,000
C) Margin of Safety in dollars = Sales Revenue - Breakeven dollars
= $225,000 - $120,000
= $105,000
d) Margin of Safety in percent
= $105,000 ÷ $225,000
= 46.67%
