Question

The population of a town increases from 2,500 to 2,800. What is the percent increase?
A
20%
B
10%
C
12%
D
15%

Answer 1

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%**.
