Answer:
B
Explanation:
It will be letter B because when it says at most it would be equal to 16 or less than 16 so, therefore, it will be letter B. The answer will not be for the burgers because since it says she plans to cook 30 burgers and not at most or at least it would mean that the answer will be either A or B.
I'm sorry, my explanation doesn't really make sense but I hope you kind of understood it.
Have a good day!
