See a solution process below:

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

#p = (N - O)/O * 100#

Where:

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

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

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

Substituting and solving for #p# gives:

#p = (5 - 4)/4 * 100#

#p = 1/4 * 100#

#p = 100/4#

#p = 25#

There was a 25% increase from 4 to 5.
