The final amount of the compound interest after 6 years would be $ 294, 122, 500

<h3>How to determine the final amount</h3>

The formula for the final amount is given as;

A = P( 1 + \frac{r}{n}) ^n^t

Where

A = final amount

P = principal interest

r = interest rate

n = number of times

t = time of periods

We have,

A = 2500 ( 1 + \frac{6}{1}) ^1^*^6

A = 2500 ( 7)^6

A = 2500 × 117, 649

A =$ 294, 122, 500

Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500
