To find the percent decrease in circulation, you can use the formula:
\[ \text{Percent Decrease} = \left( \frac{\text{Original Value} - \text{New Value}}{\text{Original Value}} \right) \times 100 \]
In this case:
- Original Value = 5200
- New Value = 3140
Now, plug the values into the formula:
\[ \text{Percent Decrease} = \left( \frac{5200 - 3140}{5200} \right) \times 100 \]
Calculating the difference:
\[ 5200 - 3140 = 2060 \]
Now, calculate the fraction:
\[ \frac{2060}{5200} = 0.3961538462 \]
Now multiply by 100 to get the percentage:
\[ 0.3961538462 \times 100 \approx 39.61538462 \]
Rounding to the nearest percent gives:
\[ \approx 40% \]
So, the percent decrease in circulation is 40%.
