How much is the man’s ticket?

One. How much is the man’s ticket?
Man: Can you tell me how much a ticket is for Saturday’s performance of Macbeth?
Woman: The front stalls and the circle are the most expensive at ￡16.50. The middle seats in the stalls cost ￡15 and the back three rows cost ￡12.50, but the view isn’t so good. All seats are ￡10 for students.
Man: I’ll have one in the middle please. I’m not a student. I’ve got my credit card here.

Five. What time was the woman’s appointment?
Woman: I’ve had an awful morning! I was really late for my hospital appointment. I just missed the 9 o’clock bus, and the next one didn’t come until 20 to 10. I was supposed to see the doctor at 10 past 10, but I didn’t arrive until half past. He wasn’t very pleased.
