1. TRUE/FALSE/UNCERTAIN: The difference in price between automaker's Tesla Model S 70 and Model S 75 is approximately $3,000. Both cars are identical and cost the same to make, but the S70 (the cheaper model) comes with additional software that limits the battery range by 20 miles (meaning the car will drive fewer miles on a full charge). By doing so, Tesla is lowering the quality of its own product but not saving any money on cost! Clearly this is a mistake.
