Answer
2.1 atm
Work Step by Step
We are given that the surface pressure of water is .97 atm and that the diver is 39 ft below the surface.
Every 33ft of H$_2$O is 1 atm. Since we have 39ft between the surface and the diver we simply find how many atm by:
39ft/33ft = 1.18 atm
Finally we just add the surface atm with the 1.18 atm to get:
1.18 atm + .97 atm = 2.1 atm
