Answer:
B. 66.67%
Explanation:
Contribution is the difference between the company's total revenue and the total variable cost. The ratio of the contribution to sales or revenue gives the contribution margin ratio.
The contribution may also be derived from the addition of the fixed cost and the operating income.
Contribution margin
= $115,000 + $54,000
= $169,000
Let the number of units to be sold to achieve targeted income be U
6U - 2U - 115,000 = 54,000
4U = 169,000
U = 42,250
Contribution margin ratio = 169000/(6 * 42,250)
= 66.67%
