You can put this solution on YOUR website! The Randolphs used 12 more gal of fuel oil in October

------------
Let amt. in Sept = x gallons
Amt in October = x+12
Amt in November = 2x
------------
EQUTION:
x + (x+12) + x = 132
3x=120
x=40 gal. in Sept
x+12 = 52 gals in October
2x = 80 gals in November
