W: Oh, hello, I would like some information on the school aquatics program.
M: Sure, now are you interested in trying out for the water polo or swim team?
W: Well, come to think of it, I would like to join some kind of team. However, I was initially just wondering when the pool had an open swim. I like to do laps a couple of times a week if possible. Now I’m thinking, water polo sounds way more interesting. M: Here’s a schedule for the times offered for open swimming. As you can see, there are several times a day you can go for a dip. Now, if you are seriously interested in water polo, the try-outs are in two weeks. There is, however, a "warm-up" practice for the next two weeks at 9:30 pm every weeknight. So, if you think you are interested in water polo, check these nights out as you can practise your skills before the official try-out.
W: Wow, that’s great! Lucky timing. Now, how much does all this cost?
M: All the fees are in that schedule I gave you, and they are quite reasonable.
W: Oh, OK.
M: The drop-in price for swimming is $2.25. However, it’s a much better deal to buy a ten-punch card for $15. The water polo warm-up practice costs the same as the open swim. Now if you make the team, you needn’t to pay these charges. However, there is a nominal fee of $45 to help pay for referees.
W: That’s great, thanks a lot for all the information.
