A rainstorm increased the amount of water stored in State J reservoirs from 125 billion gallons to 150 billion gallons. If the storm increased the amount of water in the reservoirs to 80 percent of total capacity, approximately how many billion gallons of water were the reservoirs short of total capacity prior to the storm?
Choose the correct choice from the following answers:	A) 9	B) 14	C) 25	D) 30	E) 44
After the reservoir is filled to 150 gallons the amount of water is at 80% - which means that 20% of the reservoir is empty. To figure out what that 20% is approximate: 150 gallons /80 percent = x gallons /20 percent , therefore, x = 37.5 gallons , answer choices A,B,C,D are below 37.5 . We know that the reservoir must be short more than 37.5 gallons, therefore, the only possible choice is 44.
