How much does one T-shirt cost?

W: I’d like to buy a T-shirt. But will I save any money if I buy a pair?
M: Yes. If you buy one, you have to pay six dollars, but you can have two of them for ten dollars.

M: Why did you get up at 6: 30? I thought your meeting wasn’t until 10: 30.
W: I wanted to visit the park before I left. It’s the first time I’ve seen it.
