Answer
$136839$ people
Work Step by Step
The initial population is $25000$ in the year 2000.
Each year, it grows by $12$ percent, or per year $25000$ is multiplied by $1.12$.
The population in 2015 must be predicted, thus $25000$ is multiplied by $1.12$ as much as $15$ times.
This can be expressed as:
$25000\times1.12^{15} \approx 136839$
