Answer:
The correct answer is 55%.
Step-by-step explanation:
According to the scenario, the computation of the given data are as follows:
Fixed cost = Selling expense + Administrative expense = $5,100 + $3,000
= $8,100
Now variable cost = 12 + (40× 5%) + (40 × 20%) = 12 + 2+ 8
= $22
So, we can calculate the margin of safety by using following formula:
Margin of safety = Actual Sales - Breakeven Sales
Where, Breakeven sales = $8,100 ÷ (40 - 22) = 450 units
So,Margin of safety = 1,000 - 450 units = 550 units
So, Margin of safety percentage = 550 units ÷ 1,000 units
= 0.55 or 55%
