I really love the heart of this problem but would not recommend presenting all three tasks to students at the same time. You might even start out the activity with a "notice/wonder" with no question attached, and then bridge to Task a, offering support to struggling students and giving Task b to students who get finished early. I agree with the commentary in this resource in that Task c should be tackled as a whole group lesson/discussion.

While this task does not specifically recommend graphing the equations to come to a solution, it does present the task in a modeling context which asks for exact and approximate values.

Quality of Explanation of the Subject Matter: Limited (1)
The explanation offered for Task a is procedural and does not attempt to explain why the procedure works.

Utility of Materials Designed to Support Teaching: Limited (1)
While the explanation does include guess & check as a viable solution strategy, it would be improved by including other problem solving strategies that could be used to make the problem accessible to students at varying skill levels (e.g. tables).

Quality of Instructional and Practice Exercises: Strong (2)
As the task is presenting in a modeling context and there is more than one task, some students will be able to gain conceptual understanding of systems of equations and be able to apply this knowledge to new mathematical situations.

Opportunities for Deeper Learning: Limited (1)
While opportunity for deeper learning with these tasks is strong, the explanation lacks direction on how to implement the tasks in the classroom so that students are engaged in productive struggle, problem solving, and collaboration.

The content aligns with portions of the standard. This could be improved with graphing to also show how to solve with systems of linear equations.
