What will the price be if they buy 30? What time is Mr Toyoda’s flight?

M: They are exactly what we need. The only problem is the price.
W: How much do they cost?
M: $60.
W: If we buy 30, what discount will they give us?
M: 10%.
W: What if we bought 100?
M: We’d get a higher discount, but we’d never be able to sell them all.

W: Can you order a taxi to take me to the airport, please?
M: Certainly, Mr Toyoda. What time’s your flight?
W: It leaves at four forty, but I’d better be at the airport an hour and a half before.
M: Sure. If your flight’s at four forty, you ought to be at the airport by three ten.
