in 2014 the attendance at jefferson schools fall festival was 650 in 2015 the attendance was 575 what was the percent change

Gnoma [55]

There was 11.54% decrease in attendance.

Step-by-step explanation:

Attendance in 2014 = Old value = 650

Attendance in 2015 = New value = 575

Change = New value - Old value

Change = 575 - 650 = -75

The negative sign indicates a decrease in attendance.

Decrease percentage = $\frac{Change}{Old\ value}*100$

$Decrease\ percent=\frac{75}{650}*100\\\\Decrease\ percent=\frac{7500}{650}\\\\Decrease\ percent=11.538\%$

Rounding off to nearest hundredth

Decrease percent = 11.54%

There was 11.54% decrease in attendance.
