Ms. Quarles gave the same math unit to all her classes. She grades %25 of the tests, which is 30 papers. How many students does ms. Quarles have in total?

Answer 1

If Ms. Quarles grades 25% of the tests and that is equal to 30 papers, then the total number of tests is 30 * 4 = 120 tests.

Since each student took one test, the total number of students is 120.
