Answer:
Contribution margin ratio= 0.125= 12.5%
Step-by-step explanation:
Giving the following information:
Selling price= $80
Unitary variable cost= $70
To calculate the contribution margin ratio, we need to use the following formula:
Contribution margin ratio= (selling price - unitary variable cost) / selling price
Contribution margin ratio= (80 - 70) / 80= 0.125= 12.5%
