Ms. Quarles gave the same math unit test to all her classes. She grades 25% of the tests, which is 30 papers. How many students does Ms. Quarles have in total?(1 point)
n=
120 students
To find the total number of students, we first need to determine how many tests Ms. Quarles gave in total. If 30 papers represent 25% of the tests, then 100% of the tests would be 120 papers (30 x 4 = 120). Therefore, Ms. Quarles has a total of 120 students.
