# What is the percent change of 44 to 22?

Mar 6, 2018

See a solution process below:

#### Explanation:

The formula for calculating the percent change in a value between two points in time is:

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

Where:

$p$ is the percent change - what we are solving for in this problem.

$N$ is the New Value - 22 in this problem.

$O$ is the Old Value - 44 in this problem.

Substituting and solving for $p$ gives:

$p = \frac{22 - 44}{44} \cdot 100$

$p = - \frac{22}{44} \cdot 100$

$p = - \frac{2200}{44}$

$p = - 50$

There is a negative 50% change between 44 and 22
