A rainstorm increased the amount of water stored in State J reservoirs from 180 billion gallons to 200 billion gallons. If the storm increased the amount of water in the reservoirs to 60 percent of total capacity, approximately how many billion gallons of water were the reservoirs short of total capacity prior to the storm?	Select the correct option:
A) 90
B) 114
C) 125
D) 130
E) 144
After the reservoir is filled to 200 gallons the amount of water is at 60% - which means that 40% of the reservoir is empty. To figure out what that 40% is approximate: 200 gallons /60 percent = x gallons /40 percent , therefore, x = 133.33 gallons , answer choices A,B,C,D are below 133.33 . We know that the reservoir must be short more than 133.33 gallons, therefore, the only possible choice is 144.
