Answer 2

Keywords:

Percent increase, population, increase, number thousand, rule of three

For this case we must find an estimate of the percentage increase of a population that increased from 12,089 to 15,025. For this we must round the population to the nearest thousand.

So:

12,089 can be rounded to the nearest thousand as 12,000

15,025 can be rounded to the nearest thousand as 15,000

By making a rule of three we have:

12000 --------> 100%

15000 --------> x

Where "x" represents the percentage of the new population.

$x = \frac {15000 * 100} {12000}\\x = 125%$

To know the percentage increase we subtract:

$125 -100 = 25$

So, The percent increase is 25%.
