The statement of the question is appropriate for an instructional setting but not specific enough for an assessment item. In fact, this task could be put to good use in an instructional sequence designed to develop knowledge related to students' understanding of linear functions in contexts. Though students could work independently on the task, collaboration with peers is more likely to result in the exploration of a range of interpretations. In a follow-up class discussion, the teacher could help students explore the limits of possible interpretations and speak to setting realistic parameters for mathematical models.
