Answer:
Margin of Safety as percent of sales 91.21%
Explanation:
[tex]Sales \: Revenue - Variable \: Cost = Contribution \: Margin[/tex]
If variable = 80% of sales then
sales - 80% sales = .20 sales = Contribution margin ratio
Next will be calcualte the BEP
[tex]\frac{Fixed\:Cost}{Contribution \:Margin \:Ratio} = Break\: Even\: Point_{dollars}[/tex]
800/0.2 = 4,000
Sales to achieve target income of 8,300
[tex]\frac{Fixed\:Cost + taget \: profit}{Contribution \:Margin \:Ratio} = Sales\: to\: Profit{dollars}[/tex]
(800+8,300)/.2 = 45,500
Margin of safety:
[tex]\frac{current \:sales - BEP_{USD}}{current \:sales} \times 100 = margin \: of \: safety[/tex]
[tex]\frac{45,500 - 4,000}{45,500} \times 100 = 91.21%[/tex]
