The number of years in which the money is in the account is 6 years.
Simple interest denotes the amount of payment that is received or paid by a person in return for anything pledged or given a loan.
The interest computed on the principal amount for a specified duration of time and rate of interest is called simple interest.
The formula of simple interest:
[tex]\text{SI}= \text{P}\times r \times t[/tex]
Where, (P) stands for principal, (r) for interest rate, and (t) is for the time period.
Computation of a number of years:
According to the given information,
P=$500,
r=7.5%,
t=?
SI= $225
Now, substitute the given values in the above formula, we have:
[tex]\text{SI}= \text{P}\times r \times t\\\\\$225=\$500\times\ 7.5\%\times t\\\\t= 6 \text{Years}[/tex]
Therefore, the number of years is 6 years.
