Answer:
A 12.5%
Explanation:
Given that:
Contribution margin = 40%
Sales = $312,500
Net operating income = $25,000
Average operating assets = $200,000
The formula for return on investment is
= Net operating income ÷ Average operating assets
= $25,000 ÷ $200,000
= 12.5%
Therefore, the company's net return on investment is 12.5%
