Mrs, Hughes' class has 22 students. Her principal tells her that her class will increase to 30 students. Which equation can be used to find the percent increase?

First: work out the difference (increase) between the two numbers you are comparing. Increase = New number - Original Number

Then: divide the increase by the original number and multiply the answer by 100. % Increase = Increase : Original Numberｘ100

30 - 22 = 8

8 : 22ｘ100 = 36.3636363636
