Ally’s hotel room is on the 12th floor. She parked her car in the underground parking garage 4 levels below ground level. How many floors did Ally travel in the elevator to get from her car up to her room?

1 answer

Ally traveled from the underground parking garage, which is 4 levels below ground level, to her hotel room on the 12th floor.

To calculate the number of floors Ally traveled in the elevator, we need to add the number of floors between the underground parking garage and ground level, and then add the number of floors between ground level and the 12th floor.

Since Ally parked her car 4 levels below ground level, this means she has to travel 4 floors from the garage to ground level.

From ground level to the 12th floor, there are 12 - 1 = <<12-1=11>>11 floors.

Adding the number of floors between the garage and ground level (4 floors) to the number of floors between ground level and the 12th floor (11 floors), Ally traveled 4 + 11 = <<4+11=15>>15 floors in the elevator. Answer: \boxed{15}.
