-16 floors
Ally's hotel room is on the 12th floor and her car is parked 4 floors below ground level. To get from her car up to her room, she needs to travel a total of 12 floors up from the ground level and 4 floors up from below ground level. This adds up to 12 + 4 = 16 floors. Therefore, Ally traveled 16 floors in the elevator. The correct answer is 16 floors.
To calculate how many floors Ally traveled in the elevator, you need to subtract the number of floors below ground level where her car was parked from the floor where her hotel room is located. In this case, Ally's room is on the 12th floor, and her car was parked 4 floors below ground level.
So, the calculation would be 12 - (-4) = 12 + 4 = 16 floors.
Therefore, she traveled 16 floors in the elevator to get from her car up to her room. So the correct answer is 16 floors.
