Answer:
See below
Explanation:
Clearly, 0 guests (0 adults, 0 children) will satisfy the limits on budget (≤ $3375) and number of guests (≤ 125). The only graph that includes (0, 0) in the solution set is the one shown below.
_____
When the limits are maxima, the graphs will be shaded below or to the left. The one shown is the only graph where both solution regions are below or to the left of the boundary line.
In other words, use what you know about budgets and limits to choose something that is consistent with logic and good sense.
