Problem: Given the question: W: Yes, Dr. Downs said he expects us to have the first five on the list. He is going to discuss them in detail. M: Are you going to buy them? W: I don't know. These books are expensive. And I don't have a lot of money on me. M: How about sharing them with me? W: Sounds good. M: Let's do this. I will buy three and you buy two of them. W: I would rather do it this way: we pay fifty-fifty for the books now. And at the end of the course you can take the books you find more interesting and I will take the ones I like. M: What if we both like the same books? W: Come on, we are not going to argue over that, are we? M: I was just joking. It's definitely a better idea. W: Then let's get the books as soon as possible.
