A drought decreased the amount of water in city X’s reservoirs from 118 million gallons to 96 million gallons. If the reservoirs were at 79 percent of total capacity before the drought began, approximately how many million gallons were the reservoirs below total capacity after the drought? Choose the correct option:
A) 67  B) 58  C) 54  D) 46  E) 32
let T be the total capacity of the reservoir.   Now we can equate before cases i.e 79/100(T) = 118.   Lets take approximate values for easy calculation 80/100(T) = 120 =&gt; T = 150 MG.   We need to subtract total - after drought case = 150 - 96=

54 MG..   Option 54 is correct answer...
