--------------------------------------------------------------------------
The volume (V) of a gas varies inversely as the pressure (P) on the gas.
-------------------------------------------------------------------------
V=k%2FP for some variation constant, k.

-----------------------------------------------------------------
If the volume of a gas is 12 ft3 when the pressure is 13 lb/ft2,
-----------------------------------------------------------------
VP=k
k=VP
k=12%2A13
k=156
k=156

highlight%28V=156%2FP%29--------the specific formula

------------------------------------------------------------
find the volume of the gas when the pressure is 4 lb/ft2.
-----------------------------------------------------------

You know what to do.
