Chemistry Gas Pressure Question?

There is three flasks connected in a system. Given starting conditions 0xygen V = 3.00L and P = 1.46atm, Nitrogen V = 2.00 L and P = .0908atm and Argon V = 5.00L and P = 2.71atm. What is the final pressure in the system and the partial pressure of each of the three gases? ume no change in temperature. Any help would be appreciated.
