Answer:

2nd picture, rightmost graph.

Step-by-step explanation:

This is sorta like an inequality expression. If the dot is filled in, it adds an "equal to", but if it is not filled in, then it has to be either greater than or less than.

Based off that logic, you can eliminate the first picture options since they are all filled in or not, yet the problem says "if you buy 50 buttons or less" which basically means: button less than or equal to which is important. Now, onto the second picture. You can eliminate the leftmost graph since the blank dot at the fifty is supposed to be filled, since the problem said if you buy fifty or less buttons, which is supposed to cost $50, but the dark dot is filled in the wrong place.

Anyways, I hope this explanation wasn't too confusing. If so, feel free to comment back and say what stuff you didn't get.
