See a solution process below:

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

$p = \frac{N - O}{O} \cdot 100$ $p = (N - O)/O * 100$

Where:

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

$N$ $N$ is the New Value - 5 in this problem.

$O$ $O$ is the Old Value - 4 in this problem.

Substituting and solving for $p$ $p$ gives:

$p = \frac{5 - 4}{4} \cdot 100$ $p = (5 - 4)/4 * 100$

$p = \frac{1}{4} \cdot 100$ $p = 1/4 * 100$

$p = \frac{100}{4}$ $p = 100/4$

$p = 25$ $p = 25$

There was a 25% increase from 4 to 5.
