First, we want to know in which city school the student body would prefer a system of representation based on student population. The answer would be the Middle City School, because they have the highest amount of students. If they had a system of representation based on student population, they would have the highest amount of representatives.
Then, we want to know in which city school the student body would prefer a system of representation based on a certain number of representatives per school. The answer would be the opposite of the previous question, now the system have a benefit for the schools with the lowest amount of students, the South City School, North City School and West City School. With this system, those schools would have more representatives proportionally to its population compared to the schools with the highest amount of students.
