Answer:
B, D = yes; others = no
Explanation:
Recognize that "at most" means "less than or equal to." Sarah's spending must satisfy ...
3.50 + a ≤ 9.00
Subtracting 3.50 from both sides gives ...
a ≤ 5.50 . . . . . . . . . matches the second inequality shown
__
The graph of this will be shaded to the left, where 'a' values are less than the limit. The graph will have a solid dot at 5.50, where a = 5.50 is an allowed solution. This description matches the first number line shown.

Point of clarification
We have used a red X to indicate that the corresponding inequality or graph is not an appropriate choice. It does not mean that the "NO" answer is incorrect. Rather, it means the answer is "NO."
