conversations.value: I need a clearer understanding of how to solve: The red car is 40% cheaper than the blue car. The price of the blue car is $100. How much do both cars cost?

conversations.value: The red car is 40/100 * 100 = $40 cheaper than the blue car.
  That means, that the red car costs 100 - 40 = $60.
  So both cars cost 100 + 60 = $160.
