Level 3

Baking Cookies—Scott came home from school and told his parents that he had volunteered to make cookies for everyone in the seventh grade. He needs 3 cookies for each of the 102 students in seventh grade. Scott and his parents figured out that they can fit 36 cookies on 2 baking sheets.
Is the number of cookies proportional to the number of baking sheets used? Complete the following table and determine if there is a constant of proportionality.
Explain the meaning of the constant of proportionality in this problem
