In order to calculate the compound amount and the amount of interest earned, we can use the formula below:

Where A is the compound amount after t years, P is the principal (initial amount) i is the interest rate and n is how many times the interest is compounded in a year.
So, for P = 71000, i = 0.0102, t = 4 and n = 4, we have:

Therefore the compound amount is $73952.87
The amount of interest is:

So the amount of interest earned is $2952.87.
Percents are parts of 100, so we divide 53 by 100 to find the decimal form of 53%.
53 / 100 = 0.53
