See explanation below:

The formula for calculating the change in rate over time is:

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

Where:

#p# is the percent increase or decrease over time.

#N# is the New Value

#O# is the Old Value

Substituting what we have been given:

#p = (3140 - 5200)/5200 *100#

#p = -2060/5200 * 100#

#p = -0.396 xx 100#

#p = -39.6#

The percent change was -40% or a 40% decrease in circulation.
