Solution - Compound interest (basic)

18030.01

18030.01

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 15, 575$ , $r = 5 %$ , $n = 1$ , $t = 3$ .

Compute period rate and exponent: $\frac{r}{n} = 0.05$ , $n t = 3$ , so the growth factor is $1.157625$ .

Multiply principal by growth factor: $15, 575$ × $1.157625$ = $18030.01$ .
