Boyle's law states that "for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional". Expressed as a formula, that's \(\frac{P_1}{P_2} = \frac{V_2}{V_1}\)

A mass of air has a pressure of 12.0 psi and a volume of 60 ft.^{3}. If the air is compressed to a new volume of 45 ft.^{3}, what is the new pressure?
