This Instructional Activity is a part of the Lesson 17, Unit 6, Grade 7. This problem is an introduction to the series of modeling problems in the next activity. Here, students read a question and are prompted to think about what extra information they would need to solve it. Then they write and solve inequalities to answer the question. The context in this problem provides an opportunity for students to think about aspects of mathematical modeling like discrete versus continuous solutions and rounding. Make sure to touch on these topics in discussion before moving on to the next activity.
