conversations.value: A building has four floors with ten rooms each. Legacy has to clean each room, and it takes her 6 hours to clean one room. If she earns $15 per hour of work, calculate the total amount of money she makes from cleaning all the floors in the building.
  Can you solve this problem?

conversations.value: Since the building has four floors with ten rooms each, the total number of rooms in the building is 4*10 = 40.
  If it takes Legacy 6 hours to clean each room, she will take 40*6 = 240 hours to clean all the rooms in the building.
  Since she is making $15 per hour of work, she will earn $15*240 = $3600 after cleaning all the rooms.
