Why did the girl want to make money? [originaltext]W: I need to make some money

W: I need to make some money so that I can go traveling. Do you know any part-time jobs?
M: How about sending newspapers?
W: I already thought of that, but I don’t have a bike.
M: How about walking dogs?
W: Walking dogs?
M: Yes, you know, there’ re a lot of people around here with dogs.
W: Then how much can I earn if I walk dogs?
M: More than sending newspapers. The dogs need to be walked every day, especially when people arc at work.
W: That’ s a good idea since I like dogs very much. But how can I find dogs to walk?
M: You can put an advertisement in the Sunday newspaper.
W: Then how much shall I charge for walking a dog?
M: You can try for four dollars an hour.
W: That’ s great. Thank you so much.
