69348.53

69348.53

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 18, 079$ , $r = 13 %$ , $n = 1$ , $t = 11$ .

Compute period rate and exponent: $\frac{r}{n} = 0.13$ , $n t = 11$ , so the growth factor is $3.8358611506$ .

Multiply principal by growth factor: $18, 079$ × $3.8358611506$ = $69348.53$ .
