An art teacher has $80 to spend on museum tickets for her students. Admission tickets cost $10 per student. The graph shows the linear relationship between y, the amount of money remaining for tickets, and x, the number of students going to the museum. The art teacher plans to spend all of the money on admission tickets. Which set best represents the domain of the function for this situation?

The domain of the function in this situation represents all possible values of x, which is the number of students going to the museum.

Since each student ticket costs $10, the maximum number of students the art teacher can take to the museum with $80 is 8 (80 / 10 = 8).

Therefore, the set that best represents the domain of the function is {x | 0 ≤ x ≤ 8}. This means that the number of students going to the museum can range from 0 to 8.
