This image of a McDonald's themed math problem has been floating around Facebook, and it's got everyone scrambling to remember their basic math knowledge.

Take a good hard look at this picture and post what you think the answer is in the comment section. No cheating, and no deleting your previous answer to post any changes.

Don't give away how you got your answer either. Let everyone else attempt to come to their own conclusions while you sit back and have a good laugh at the ridiculous answers that come pouring in.

Well ... Did you figure it out? Again, just share your answer, and feel free to argue with folks that disagree with you in the comments.

HINT: Please excuse my dear aunt Sally.
