Answer:
contribution margin 149,000
contribution margin ratio 73.76%
Explanation:
[tex]Sales \: Revenue - Variable \: Cost = Contribution \: Margin[/tex]
sales revenue 292,000
variable cost 99,000
variable selling 44,000
contribution margin 149,000
The variable S&A cost are part of the variable cost, so they are deducted from the sales revenue to obtain the contribution margin
[tex]\frac{Contribution \: Margin}{Sales \: Revenue} = Contribution \: Margin \: Ratio[/tex]
149,000/292,000 = .737624 = 73.76%
