How did you set up and work through the problem? Here is a solution skeleton that reveals possible steps in solving the problem.
In our scenario, the teacher, Carlos Cabana, has decided to present this problem in a group test. He has organized his class of thirty-four students into groups of three and four. They are working on the problem together. He will give each group one grade, to be determined by grading a different problem on each student's test.
Effective communication within the group was essential as Mr. Cabana had chosen a problem that was beyond the capacity of the students to solve individually.
Questions to consider:
Put yourself in Mr. Cabana's shoes and answer these questions.
