Problem: 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 ?
Options: a ) 90 , b ) 114 , c ) 125 , d ) 130 , e ) 144
Rationale: 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 e .
