In 2000, the number of students enrolled at Arlington Country Day School was 823 students. In 2010, the population was approximately 705 students. Find the percent of change in the enrolled students at Arlington Country Day School from 2000 - 2010 and identify it as an increase or decrease.

Answer 1

705 - 823 = -118

-118/823 = -0.143 = 14.3% decrease

Answer 2

14.33%. Decrease.

Explanation:

Before, students were 823

After, students were 705

Definitely, there is a decrease. To find percentage decrease, we use the formula:

Percentage change =
`(After-Before)/(Before)`

So we have:

`(705-823)/(823)=-0.1433*100=-14.33`

Percentage change in the enrolled students at Arlington Country Day School from 2000 - 2010 is 14.33%. It is a decrease.
