87759.86

87759.86

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 19, 360$ , $r = 13 %$ , $n = 2$ , $t = 12$ .

Compute period rate and exponent: $\frac{r}{n} = 0.065$ , $n t = 24$ , so the growth factor is $4.5330508058$ .

Multiply principal by growth factor: $19, 360$ × $4.5330508058$ = $87759.86$ .
