Question

Huntsville’s population grows from 25,000 to 28,000. What is the percent increase in Huntsville’s population?

Answer 1

Answer:

$\%increase = 12\%$

Step-by-step explanation:

The formula to calculate the percentage of increase is:

$\% = \frac{x_f-x_i}{x_i}*100\%$

Where

$x_i$ is the initial amount and $x_f$ is the final amount

So:

$\% = \frac{28000-25000}{25000}*100\%$

$\% = \frac{3000}{25000}*100\%$

You can write it as:

$\% = \frac{3*1000}{25*1000}*100\%$

This is:

$\% = \frac{3}{25}*100\%$

$\%increase = 12\%$
