Question 762371: At the surface of the ocean, the water pressure is the same as the air pressure above the water, about 15 \quad lb/in^2, Below the surface the water pressure increases by about 5.34 \quad lb/in^2 for every 10 ft of descent.
Write a function f(x) which expresses the water pressure in pounds per square inch as a function of the depth in inches below the ocean surface.
I am trying to come up with a formula and am very stuck. Please help.

You can put this solution on YOUR website!
f(x) = 15 + 5.34 * (x / 120) where x is depth in inches and 120 is 10 feet in inches
