Answer: 17, 13, 9, 5, 1
Step-by-step explanation:
y=-2(-2) + 9 = 13
y=-2(0) + 9 = 9

The travels you have described are:
                                       (Middle floor) + 8 + 5 - 9 + 7 - 32
                                   =  (middle floor)  + 20 - 41
                                   =  (middle floor)  -  21  brought her to floor #1.
So                                   Middle floor  -  21  =  1
Add 21 to each side:    Middle floor  =  22  
The building has (2 x middle floor)  =  44 floors.
