First you need to figure out how many cookies will serve a single student.
You divide 84 by 28 and get 3.
So if 3 cookies serves an individual student, you multiply 3×30 and get 90. 90 cookies serve 30 students.

For this question you will need to find out how many cookies each student eats. To find this, do 84 divided by 28. You will get 3. Since 28 is 2 less than 30, add 6 cookies for the two extra students. You will need 90 cookies.
