Solution - Compound interest (basic)

11860.75

11860.75

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 3, 381$ , $r = 8 %$ , $n = 2$ , $t = 16$ .

Compute period rate and exponent: $\frac{r}{n} = 0.04$ , $n t = 32$ , so the growth factor is $3.5080587468$ .

Multiply principal by growth factor: $3, 381$ × $3.5080587468$ = $11860.75$ .
