conversations.value: Bob is in charge of doing laundry for a large hotel. Each room has two sheets, one comforter, twice as many pillow cases as sheets and twice as many towels as pillow cases. How many pieces of laundry are there in 80 rooms?
  How to solve this?
conversations.from: assistant
conversations.value: First find the number of pillow cases in each room: 2 sheets * 2 pillow cases/sheet = 4 pillow cases
  Then find the number of towels in each room: 4 pillow cases * 2 towels/pillow case = 8 towels
  Then find the number of pieces of laundry in each room: 4 pillow cases + 8 towels + 2 sheets + 1 comforter = 15 pieces of laundry
  Then multiply the number of pieces of laundry in each room by the number of rooms to find the total: 15 pieces of laundry/room * 80 rooms = 1200 pieces
