This Instructional Activity is a part of the Lesson 1, Unit 3, Grade 6. The purpose of this task is to give students a good reason to compute a rate "per 1". Since the task statement doesn't provide all the information needed to answer the question and does not suggest a solution pathway, it is an opportunity for students to make sense of the problem and engage in some aspects of mathematical modeling.
