Post each question as a separate thread. It is easy to focus and helpful for people who search. Also, try to elaborate where you are having difficulties while solving these so people can help you better.

The hamburger question seems to have a typo... none of the answer choices work. I believe this was brought up before. It's likely that the burger plus coleslaw is $3.95 and not $3.59.
