202312.38

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 16, 483$ , $r = 12 %$ , $n = 12$ , $t = 21$ .

Compute period rate and exponent: $\frac{r}{n} = 0.01$ , $n t = 252$ , so the growth factor is $12.2740020992$ .

Multiply principal by growth factor: $16, 483$ × $12.2740020992$ = $202312.38$ .
