conversations.value: A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?
  Give me a clear explanation.

conversations.value: They sold $200 worth of cars each month because 4 x 50 = 200
  They made $100 a month off cars because 200 - 100 = 100
  They sold $400 worth of motorcycles each month because 8 x 50 = 400
  They make $150 a month off motorcycles because 400 - 250 = 150
  They make $50 more a month off motorcycles than cars because 150 - 100 = 50
