in 200, the population at Arlington Middle School was approximately 421 students. In 2010, the population was approximately 584 students. Find the percent of change in the population at Arlington Middle School from 2000-2010 and identify it as an increase or decrease
1 27.9% increase
2 27.9% decrease
3 38.7% increase
4 38.7% decrease
584/421 = 1.387
which is a 38.7 % increase
another way
584 - 421 = 163
163/421 = .387 so 38.7% increase
Both ways are actually the same but different ways of thinking about it :)

To find the percent of change in the population at Arlington Middle School from 2000 to 2010, you need to calculate the percentage difference between the two population numbers.
First, subtract the population in 2000 (421) from the population in 2010 (584):
584 - 421 = 163
Then, divide the difference (163) by the population in 2000 (421):
163 / 421 = 0.387 (rounded to three decimal places)
Multiply the result by 100 to get the percentage:
0.387 * 100 = 38.7%
Therefore, the percent of change in the population at Arlington Middle School from 2000 to 2010 is 38.7%.
Since the result is positive, it signifies an increase in population. So the correct answer is:
3. 38.7% increase
