210890.79

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 15, 438$ , $r = 14 %$ , $n = 4$ , $t = 19$ .

Compute period rate and exponent: $\frac{r}{n} = 0.035$ , $n t = 76$ , so the growth factor is $13.6604996424$ .

Multiply principal by growth factor: $15, 438$ × $13.6604996424$ = $210890.79$ .
