Final answer:
The question does not answer any given questions as it lacks sufficient data. Choice D, indicating 'None', is the correct answer since additional information about costs and sales necessary for a complete analysis is not provided.
Step-by-step explanation:
The question you've asked seems to be related to comparing costs between members and non-members, with the key information being that a member pays an additional $60 for membership. The question seems to be testing understanding of basic economic or cost analysis principles, typical of a high school mathematics problem that deals with real-world applications of algebraic or arithmetic concepts. When comparing choice D with B, it's noted that choice B isn't the best answer because it lacks sufficient information to conclude the profit margins (since costs and sales numbers are unknown).
Therefore, the correct answer to 'How many questions does this answer?' is D) None, as the information given, does not suffice to answer questions that would determine the profitability of a company or the comparative values of memberships versus non-member costs without additional data.
