The return on assets (ROA) for each division can be calculated by dividing the net income by the assets:
ROA = Net Income / Assets
For the Basketball division, the ROA is:
ROA = $4,000,000 / $20,000,000 = 0.20 or 20%
For the Soccer division, the ROA is:
ROA = $1,500,000 / $15,000,000 = 0.10 or 10%
For the Cross-trainer division, the ROA is:
ROA = $750,000 / $10,000,000 = 0.075 or 7.5%
Therefore, the return on assets for the Basketball division is 20%, for the Soccer division is 10%, and for the Cross-trainer division is 7.5%.
