Chem Gas Laws?

A particular balloon can be stretched to a maximum surface area of 1257 cm^2. The balloon is filled with 3.2 L of helium gas at a pressure of 759 torr and a temperature of 292K . The balloon is then allowed to rise in the atmosphere. ume an atmospheric temperature of 273 K and determine at what pressure the balloon will burst. (ume the balloon to be in the shape of a sphere.) This is confusing. It doesn't look like any gas laws I know!
