To calculate the percent increase in the population of the town, you can use the formula:

\[ \text{Percent Increase} = \left( \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \right) \times 100 \]

In this case, the old value (initial population) is 2,500 and the new value (final population) is 2,800.

  1. Calculate the increase in population: \[ \text{Increase} = 2,800 - 2,500 = 300 \]

  2. Now, plug the values into the percent increase formula: \[ \text{Percent Increase} = \left( \frac{300}{2,500} \right) \times 100 \]

  3. Calculate the fraction: \[ \frac{300}{2,500} = 0.12 \]

  4. Multiply by 100 to find the percentage: \[ 0.12 \times 100 = 12% \]

Therefore, the percent increase in the population is 12%. The correct answer is C 12%.
