# 8 is increased to 22, what is the percent change?

Oct 28, 2016

The precent change was 175%

#### Explanation:

The formula for percent change is $p = \frac{N - O}{O} \cdot 100$ where $p$ is the percentage change, $N$ is the new value and $O$ is the old value.

Substituting what we know gives:

$p = \frac{22 - 8}{8} \cdot 100$

$p = \frac{14}{8} \cdot 100$

$p = 1.75 \cdot 100$

$p = 175$
