Solution - Compound interest (basic)

17159.02

17159.02

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 6, 992$ , $r = 6 %$ , $n = 12$ , $t = 15$ .

Compute period rate and exponent: $\frac{r}{n} = 0.005$ , $n t = 180$ , so the growth factor is $2.4540935622$ .

Multiply principal by growth factor: $6, 992$ × $2.4540935622$ = $17159.02$ .
