38163.46

38163.46

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 7, 809$ , $r = 12 %$ , $n = 1$ , $t = 14$ .

Compute period rate and exponent: $\frac{r}{n} = 0.12$ , $n t = 14$ , so the growth factor is $4.8871122851$ .

Multiply principal by growth factor: $7, 809$ × $4.8871122851$ = $38163.46$ .
