anonymous · Answer

C cannot be the answer because we ALREADY know the number of cars on the 3rd and 1st level

B

anonymous · Answer

B is the best answer because, once you have the total number of cars, you can combine the 1st and 3rd number of cars
subtract that from the total
and arrive at the number of cars on the second level
