Answer:
b. 8%
Explanation:
Percentage contribution is determined as the associated fixed costs divided by the break-even revenue. The break-even revenue is given by the product of the break-even volume by the unit selling price. The percentage contribution is:
[tex]\%C=\frac{FC}{N*P} \\\%C=\frac{\$100,000}{50,000*\$25.00}\\\%C = 8\%[/tex]
Note that the sales force commission does not interfere in the contribution.
The answer is b. 8%
