Brian: Hi Danny and Jenny. Do you know that our basketball team is going to play in another city?
Jenny: Yes. But the trip costs a lot of money. Each player needs to pay ＄150. We need to make some money for the team!
Danny: How can we make money? I don't have a job.
Brian: Maybe we can work together to raise some money. Have you got any ideas, Jenny?
Jenny: Maybe we can have a bake sale. We can sell snacks and other things at lunch hour.
Brian: Good idea, Jenny! I'll bake something delicious. I think everybody likes cookies.
Danny: Yes! How much will they cost?
Brian: One dollar for four cookies.
Danny: I'm going to buy sixteen!
Jenny: We need some advertising. I'll make a poster. What will you sell, Danny?
Danny: I'm going to invent a new product!
Brian: Really?
Jenny: Hmm…
