382264.06

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 21, 907$ , $r = 10 %$ , $n = 1$ , $t = 30$ .

Compute period rate and exponent: $\frac{r}{n} = 0.1$ , $n t = 30$ , so the growth factor is $17.4494022689$ .

Multiply principal by growth factor: $21, 907$ × $17.4494022689$ = $382264.06$ .
