38920.09

38920.09

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 15, 912$ , $r = 7 %$ , $n = 2$ , $t = 13$ .

Compute period rate and exponent: $\frac{r}{n} = 0.035$ , $n t = 26$ , so the growth factor is $2.4459585587$ .

Multiply principal by growth factor: $15, 912$ × $2.4459585587$ = $38920.09$ .
