    Not a difficult inequality, just drawing a blank

    "Edgewood High School is planning a field trip to Everglades National Park. On the trip, there must be a minimum of one adult for every eight students. The buses can carry a maximum of 480 people.
    "A. Define Variables and write a system of inequalities to represent this situation."

    Supposing Adults = A & Students = S, I have:
    A+S<480
    A>8S

    Is this even wrong? Blah, it just doesn't seem right.

    hi

     A+S \leq 480

     8A \geq S

    If for example there are 16 students, S=16,  A \geq \frac{16}{8} =2
