Answer:
Sub America's net income for the year is A. $42,500
Step-by-step explanation:
Return on assets (ROA) helps an investor see how much after-tax profit a company gained for each dollar in assets, is calculated by formula:
ROA = Net Income/ Average Total Assets
In there:
Average Total Assets = (Beginning Assets + Ending Assets )/2 = (Assets at the beginning of year +Assets at end of year )/2
In Sub America,
Average Total Assets = ($400,000+$450,000)/2 = $425,000
ROA = 10%
Net income = ROA x Average Total Assets = 10% x $425,000 = $42,500
