For every 33 feet a scuba divers descends below the surface of water, the water pressure increases by 15 pounds per square inch. a diver reaches the bottom of a lake that is 99 feet deep. what is the water pressure?

The water pressure is 45 pounds per square inch. The way to solve this problem is to first divide the distance covered by the diver which is 99 feet to the distance with corresponding pressure which is 33 feet. Then multiply what you get with 15 lbs per in^2.
