This question doesn't want the exact number, but a "guesstimate." You can calculate this by asking what number close to 222 can 3 (the number of students) be divided equally into--this would be 210. 210/3 = 70, and since 222 is greater than 210 (but less than 240, which would be 240/3=80), the answer would be C. More than 70 and less than 80.
