Solution - Compound interest (basic)

7340.59

7340.59

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 6, 722$ , $r = 9 %$ , $n = 2$ , $t = 1$ .

Compute period rate and exponent: $\frac{r}{n} = 0.045$ , $n t = 2$ , so the growth factor is $1.092025$ .

Multiply principal by growth factor: $6, 722$ × $1.092025$ = $7340.59$ .
