Answer:
25%
Explanation:
the formula for the margin of safety is as follows
margin = current sales level -breakeven point/ current sales level x 100
expected sales unit = 20,000 units
the break-even point is fixed costs/contribution margin
fixed costs= $360,000
contribution margin = sales price- variable costs
=61-37
=24
breakeven point = $360,000/ 24
=15000
the margin of safety = 20,000-15,000/20,000 x 100
=5000/20000 x 100
=25%
