Answer: the percent change in attendance from 2014 to 2015 is 11.54%
Explanation:
In 2014, the total attendance at Jefferson school's Fall festival was 650.
In 2015, the attendance was 575. The change in the number of attendees between 2014 and 2015 is 650 - 575 = 75
There was a decrease in the number of attendees between 2014 and 2015.
The percent change in attendance from 2014 to 2015 would be attendance in 2015 divided by attendance in 2014 and multiplied by 100. It becomes
75/650 × 100 = 11.54%
