138387.87

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 23, 489$ , $r = 6 %$ , $n = 2$ , $t = 30$ .

Compute period rate and exponent: $\frac{r}{n} = 0.03$ , $n t = 60$ , so the growth factor is $5.891603104$ .

Multiply principal by growth factor: $23, 489$ × $5.891603104$ = $138387.87$ .
