120 students
Solution:
If 30 papers represent 25% of the total number of students, then each 1% is equal to 1.2 students (30 students / 25%). Therefore, to find the total number of students, you need to divide 100% by 1.2 students per percent.
100% / 1.2 = 83%
So, Ms. Quarles has a total of 83 students in total across all her classes.
