Marlye posted a story on her blog. On the first day there were 80 responses and on the second day there were 180 responses. What percent is the increase, 100, of the original number of responses, 80?

100(180-80)/80 = 125 %

To find the percent increase, you need to calculate the difference between the two values and then express it as a percentage of the original value.

Step 1: Find the difference between the two values.
180 (number of responses on the second day) - 80 (number of responses on the first day) = 100

Step 2: Calculate the percent increase.
To find the percent increase, divide the difference by the original value and multiply by 100.
(100 / 80) * 100 = 125%

The percent increase is 125%.
