Solution - Compound interest (basic)

22520.60

22520.60

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 6, 013$ , $r = 9 %$ , $n = 2$ , $t = 15$ .

Compute period rate and exponent: $\frac{r}{n} = 0.045$ , $n t = 30$ , so the growth factor is $3.7453181345$ .

Multiply principal by growth factor: $6, 013$ × $3.7453181345$ = $22520.60$ .
