50740.08

50740.08

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 11, 431$ , $r = 8 %$ , $n = 2$ , $t = 19$ .

Compute period rate and exponent: $\frac{r}{n} = 0.04$ , $n t = 38$ , so the growth factor is $4.4388134504$ .

Multiply principal by growth factor: $11, 431$ × $4.4388134504$ = $50740.08$ .
