Well, I'm pretty sure it should stay non-negative.

The possible number of students added can be equal to or less than 4. Which graph shows equal to or less than 4?

tackopp · Answer

D?

thefurball · Answer

(Hint: Closed dot means it includes the number 4)

Oh wait I misread the question. It should be greater than (not equal to) 4 in order to require multiple busses.

Throw out B and D without even considering them.  Could -12 be a good answer?

tackopp · Answer

so C
