The pressure on a scuba diver at sea level is 14.7 pound psi.The pressure increases 0.0445 psi for each foot of depth. Suppose the diver is 32.5 psi. How deep is he?

Answer 1

P = .0445 x + 14.7 , where x is the number of feet of depth

32.5 = .0445x + 14.7
solve for x

hint: comes out to a nice number
