interest is p*r*t
Here, it would be 500(1.013)^4, which is the 1.3% interest rate over 4 years.
The amount after 4 years would be $526.51, so the interest earned would be $26.51

The other tutor used compound interest instead of simple interest....

With simple interest of 1.3% for 4 years, the interest is 5.2% of the original amount (1.3%, times 4).

i = p*r*t: interest equals (principal) times (rate) times (time)

i+=+500%28.013%29%284%29+=+26

The amount of interest is $26.
The percent change in the value of the account is 5.2%.
