On the second floor we have 6 apartments, and we have 2 more apartments with 3 bedrooms, so 8/16 apartments are either on the second floor or have 3 bedrooms. 8/16 is the same as 1/2, or 50%
Constant is occurring continuously over a period of time so C is the correct answer because C is constant for a period of time
No Nothing Further Can Be Done
The volume is 96.
v=l*w*h
v=6*3*3=54
v=2*3*7=42
54+42=96
Hope this helps
