answer: #Person2# tells #Person1# the parking lot in the community isn't always busy, so #Person2# decides to rent some of the spaces out at the hourly rates.
documents: #Person1#: How big is this parking lot in our community?
  #Person2#: It has fifty parking spaces.
  #Person1#: So you guys should be always busy.
  #Person2#: Why?
  #Person1#: I bet it is always full of cars.
  #Person2#: Quite the contrary, sir. Plenty of the spaces here are free when people drive their cars out to work.
  #Person1#: Ah. . . I see.
  #Person2#: We plan to rent some of them out at the hourly rates.
  #Person1#: What is the hourly rate for a car like this?
  #Person2#: I am not sure. But it'll be at least ten yuan an hour.
  #Person1#: How mush would it cost if someone parks here for one hour and ten minutes?
  #Person2#: That would be twenty yuan, sir. We charge only by the number of hours, no split of each hour.
  #Person1#: That's expensive.
