Solve Applications with Rational Equations · Exercise 80

Write an inverse variation equation to solve the following problems.

Boyle’s law states that if the temperature of a gas stays constant, then the pressure varies inversely to the volume of the gas. Braydon, a scuba diver, has a tank that holds air under a pressure of 220 psi.
ⓐ Write the equation that relates pressure to volume. ⓑ If the pressure increases to 330 psi, how much air can Braydon’s tank hold?

Its source prints no answer for this problem, so there's nothing to check against.
