314612.17

314612.17

Step-by-step explanation

Use $A = P {(1 + r / n)}^{(n t)}$ with $P = 23, 158$ , $r = 11 %$ , $n = 1$ , $t = 25$ .

Compute period rate and exponent: $\frac{r}{n} = 0.11$ , $n t = 25$ , so the growth factor is $13.5854638029$ .

Multiply principal by growth factor: $23, 158$ × $13.5854638029$ = $314612.17$ .
