Answer:
b. 49.3%
Step-by-step explanation:
The computation of contribution margin ratio is shown below:-
For computing the contribution margin ratio first we need to find out the total contribution which is here below:-
Total Contribution = Sales - Direct Material - Direct labor - Variable Overhead - Variable
= $3,500,000 - $500,000 - $250,000 - $275,000 - $750,000
= $1,725,000
Contribution margin Ratio = Contribution ÷ Sales
= $1,725,000 ÷ $3,500,000
= 49.3%
So, for calculating the contribution margin ratio we simply divide total contribution by sales.
