<bot>: How much is the red car cheaper than the blue car? ** The red car is 40/100 * 100 = $<<40/100*100=40>>40 cheaper than the blue car.
How much does the red car cost? ** That means, that the red car costs 100 - 40 = $<<100-40=60>>60.
How much do both cars cost? ** So both cars cost 100 + 60 = $<<100+60=160>>160.
