# What is the percentage change from 50 to 60?

Feb 25, 2017

There was a 20% increase

#### Explanation:

The formula for the change in values over a period of time is:

$p = \frac{N - O}{O} \times 100$

Where:

$p$ is the percentage change - what we are solving for in this problem.
$N$ is the New value - $60$ for this problem.
$O$ is the Old value - $50$ for this problem.

Substituting and calculating $p$ gives:

$p = \frac{60 - 50}{50} \times 100$

$p = \frac{10}{50} \times 100$

$p = \frac{1000}{50}$

$p = 20$
