For a fixed amount of a gas at a constant
temperature, the volume of the gas is inversely
proportional to its pressure. At a pressure of 30
pounds per square inch (psi), a gas has a volume
of 600 in.3.
Which function can be used to model the volume
of the gas y, in cubic inches, when the pressure is
x psi?
what would the volume of the gas be if the pressure is increased to 40 P
