Answer :
Answer:
contribution margin ratio= 0.45
Explanation:
Giving the following information:
Blanc Company Noir Company
Company Sales $485,000 $485,000
Variable costs 291,000 242,500
To calculate the contribution margin ratio, first, we need to determine the sales proportion:
Blanc= 485,000/970,000= 0.5
Noir= 485,000/970,000= 0.5
Now, we need to use the following formula:
contribution margin ratio= Weighted average contribution margin/ Weighted average sales
Weighted average contribution margin= (weighted average sales - weighted average variable cost)
Weighted average contribution margin= (0.5*485,000 + 0.5*485,000) - (0.5*291,000 + 0.5*242,500)
Weighted average contribution margin= 218,250
contribution margin ratio= 218,250 / 485,000
contribution margin ratio= 0.45
