Answer:
Return On Investment = 22.5%
Step-by-step explanation:
Given:
Sales = $750,000
Contribution margin = $150,000
Total direct fixed costs = $90,000
Average total operating assets = $400,000
Find:
Return On Investment if contribution margin increase by $30,000
Computation:
Net operating income = Contribution margin - Total direct fixed costs
Net operating income = [$150,000 + $30,000] - $90,000
Net operating income = $90,000
Return On Investment = [Net operating income / Net operating assets]100
Return On Investment = [90,000 / 400,000]100
Return On Investment = [0.225]100
Return On Investment = 22.5%
