Answer:
ROI = 75%
Step-by-step explanation:
Andrew invested $20,000 in mutual funds and received a sum of $35,000 at the end of the investment period.
His gain from mutual fund = $35,000 - $20,000 = $15,000.
Return of Investment (ROI) = (Gain Amount / Investment Amount) *100
ROI = ($15,000 / $20,000) *100
ROI = 0.75 *100
ROI = 75%
Hence, his ROI from mutual fund was 75% of his investment.
