Kate and joey are staying at a hotel for the weekend. Kate is on the 7th floor and joey is in the garage which is 3 floors underground. How many floors are between them
There are 7 floors between Kate and the lobby since 7 - 0 = <<7-0=7>>7
The garage is 3 floors underground, so there are 3 + 1 = <<3+1=4>>4 floors between joey and the lobby.
Therefore, there are 7 + 4 = <<7+4=11>>11 floors between Kate and Joey. Answer: \boxed{11}.
