conversations.value: Tom decides to get a new floor for his room.  It cost $50 to remove the floor.  The new floor costs $1.25 per square foot and Tom's room is 8*7 feet.  How much did it cost to replace the floor?
  Give me a solution to this problem

conversations.value: The room is 8*7=56 square feet
  So the new carpet cost 56*1.25=$70
  So the total cost was 50+70=$120
