457551.40

457551.40

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 18, 054$ , $r = 13 %$ , $n = 12$ , $t = 25$ .

Compute period rate and exponent: $\frac{r}{n} = 0.0108333333$ , $n t = 300$ , so the growth factor is $25.3434914715$ .

Multiply principal by growth factor: $18, 054$ × $25.3434914715$ = $457551.40$ .
