Answer: 182 gallons
find 30% of 260 by multiplying 260 by 30%
260 x .3 = 78
30% of 260 = 78
Subtract 78 from 260 to get original amount
260 - 78 = 182
Original is 182 gallons
ps. this is an actual impossible question because you need to know the original amount to find what 30% of it is. What i found was a 30% decrease of 260 not a 30% increase of the original. With that being said I think this is what you want?
