Question

The airplane Li's family will be flying on can seat up to 149 passengers. If 96 passengers are already on the plane, which graph represents the solution to the inequality that would be used to find how many more people can board?

A number line going from 50 to 60. An open circle is at 53. Everything to the left of the circle is shaded.

Answer 1

Let x = number of additional passengers. 96 + x ≤ 149 → x ≤ 53.

So the correct graph is: a solid circle at 53 with everything to the left shaded (third option).
