See explanation below:

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

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

Where:

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

$N$ $N$ is the New Value

$O$ $O$ is the Old Value

Substituting what we have been given:

$p = \frac{3140 - 5200}{5200} \cdot 100$ $p = (3140 - 5200)/5200 *100$

$p = - \frac{2060}{5200} \cdot 100$ $p = -2060/5200 * 100$

$p = - 0.396 \times 100$ $p = -0.396 xx 100$

$p = - 39.6$ $p = -39.6$

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