The Randolphs used 12 more gal of fuel oil in October
than in September and twice as much oil in November as in September. If they
used 132 gal for the 3 months, how much was used during each month?
------------
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
