What ages is the computer game suitable for?

W: Hi, Mark. What are you doing?
M: Hi, Jenny. Shopping for a present for my little brother.
W: I bought my brother a computer game called City 2010. He plays with it for hours.
M: How old is he?
W: 10.
M: Oh, my brother is 12.
W: That’s OK. This game is good for 8-13 year olds.
M: Great. Where did you buy it?
W: In Black’s PC shop. I looked everywhere in Cambridge and Peterstown. But in the end, I have to go to a shop in London.
M: Where is the shop?
W: In Marsden Street. You know Hunter Boad? Turn left at the end, and its opposite worker’s department store at Number 30.
M: I can go there next Thursday.
W: That’s good. Next week from Monday to Friday, you get a second game free. M- Great! How much was your brother’s game?
W: I bought two games that day and paid 48 pounds altogether. So my brother’s game was 24 pounds.
M: Oh, less than 30. That’s not bad. Thanks, Jenny.
