227039.43

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 19, 874$ , $r = 14 %$ , $n = 2$ , $t = 18$ .

Compute period rate and exponent: $\frac{r}{n} = 0.07$ , $n t = 36$ , so the growth factor is $11.4239421885$ .

Multiply principal by growth factor: $19, 874$ × $11.4239421885$ = $227039.43$ .
