Answer:
Contribution margin ratio is 38%
Step-by-step explanation:
The contribution margin ration is the ratio of contribution over sales revenue.
The contribution in this parlance is difference between the sales revenue and variable costs.
Contribution=sales-variable costs
sales =volume * price
volume is 18000 pairs
price per unit is $52
However the variable is not given
Break-even units=fixed costs/(sales price-variable cost)
let variable cost per unit to be x
18000=360,000/(52-x)
(52-x)*18000=360000
52-x=360000/18000
52-x=20
x=52-20
x=32
contribution=52-32
contribution =$20
contribution margin ratio=20/52
=0.38 or 38%
