Answer:

25

Step-by-step explanation:

Let's set up "x" as the total number of students. So now we can set up an equation:

40%x+15=x rewritten as:

.4x+15=x Subtract .4x from both sides will give us:

 

15=.6x Now divide each side by .6 to be:

25=x Therefore we know there are 25 students in the class.

Make sense?
