The water level in a plastic pool changed by -8 gallons each hour due to a small hole in the bottom. After 6 hours, the pool contained 132 gallons. How muc was in the pool originally?
The answer is very easy to find. If the water drains 8 gallons every hour and after 6 hours it is 132 gallons full, the origional amount of water is 180 gallons of water
