amount of water in the reservoirs to
82 percent of total capacity,
approximately how many billion
gallons of water were the reservoirs
short of total capacity prior to the
storm?

138 billion gallons = 82% of total capacity
X billion gallons = 100% capacity

138/X = 82/100
X = 168.AB

How many billion gallons of water were the reservoirs short of total capacity prior to the storm?
168.AB - 124 billion gallons ~44.AB billion gallons

Answer E

138 billion gallons = 82% of capacity.
therefore 100% of the capacity = (138/82)*100 = (69/41)*100 ~ (70/40)*100 ~ 175 Billion gallons.
