Answer:
Contribution margin ratio = 69.2 %
Step-by-step explanation:
Contribution margin ratio is the percentage of sales revenue that is earned as contribution. Contribution is sales less variable cost
Contribution margin ratio =( (Sales - variable cost)/ Sales ) × 100
Contribution = sales less variable cost
Sales revenue = (18.50× 30,000) = 555,000
Variable cost = 114,000+ 23,000 +34,000 = 171,000
Fixed cost = 115,000 +21,000 + 16,000 = 152,000
Contribution margin ratio
=(555,000 - 171,000)/555,000 × 100
= 0.691 × 100
= 69.2 %
Contribution margin ratio = 69.2 %
