Last year there were 1,435 8 grade students enrolled at your school . this year there are what is the percent change in the number of 8th grade?

There was about a 15% change in the number of students, I believe.

 each % is 14 8 graders  the % of 8 graders this year is 85.72% 
there is a 14.28% difference from last year and this year 
 

Where are the following equations?

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
