Answer:
$125,000
Explanation:
total sales = ?S
variable expenses = S x 40%
fixed costs = $270,000
operating income = $75,000
S - 0.4S - $270,000 = $75,000
0.6S = $75,000 + $270,000 = $345,000
S = $345,000 / 0.6 = $575,000
total sales = $575,000
margin of safety = total sales - break even point
break even point = $270,000 / 0.6 = $450,000
margin of safety = $575,000 - $450,000 = $125,000
The margin of safety represents how much can a company's sales can fall until it reaches the break even point.
