Where, (P) stands for principal, (r) for interest rate, and (t) is for the time period.
<u>Computation </u><u>of a number of years:</u>
According to the given information,
P=$500,
r=7.5%,
t=?
SI= $225
Now, substitute the given values in the above formula, we have:
Therefore, the number of years is 6 years.
