Calculate the ROI, given the following: Andrew invested $20,000 in mutual funds and received a sum of $35,000 at the end of the investment period.

We are given with an initial deposit of $20,000 and a future worth of $35,000. In this case, we are asked for the return of income (ROI) of the investment. in this case, we assume the number of years equal to 1. hence,

$35,000 = $20,000 * (1+i) ^1

i or ROI then is equal to 0.75
