# What is the percentage change from -63 and -66?

Jun 15, 2017

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: -66 in this problem.

$O$ is the Old Value: -63 million in this problem.

Substituting and solving for $p$ gives:

$p = \frac{- 66 - - 63}{-} 63 \cdot 100$

$p = \frac{- 66 + 63}{-} 63 \cdot 100$

$p = \frac{- 3}{-} 63 \cdot 100$

$p = \frac{300}{63}$

$p = 4.8$ rounded to the nearest tenth.

There was a 4.8% change.
