131521.54

131521.54

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 20, 444$ , $r = 11 %$ , $n = 12$ , $t = 17$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0091666667$ , $n t = 204$ , so the growth factor is $6.4332585737$ .

Multiply principal by growth factor: $20, 444$ × $6.4332585737$ = $131521.54$ .
