Here is a simple question I am struggling with:
Allison, Jonathan, and Jennifer are teachers at a school. There classes contain a total of 82 students. Jonathan's class is 25% larger than Jennifer's class. Allison's class has 9 more students than Jennifer's class. How many students are in Allison's class?
A. 35 students B. 26 students C. 31 students D. 14 students E. 25 students
Here is how I tried to solve:
Let Allison's class be x, Jonathan's be y and Jenn's be z.
$0.75y=z$ (y should be 25% larger than z)
And then, I tried to solve it for $x$ but didn't get the right answer. What I seem to be missing is the percent part:
When it says, Jonathan's class is 25% larger than Jennifer's class, does it mean 25% OF Jonathan's class or Jonathan's class is 125% OF Jennifer's?
