This Instructional Activity is a part of the Lesson 7, Unit 2, Grade 7. This activity provides the first example in this unit of a relationship that is not proportional. The second question focuses students' attention on the unit rates. If the relationship were proportional then regardless of the number of people in a vehicle, the cost per person would be the same. The question about the bus is to show students that they can't just scale up from 10. Students who write an equation also see that it is not of the form y = kx.
