    I'm going to represent this situation as an equation:

    x = the number of gallons

    y = the total cost

    1.42x = y

    1.42x = 14.95

    [They charge $1.43 per gallon (x), and she payed a total (y) of $14.95]

    You need to find the number of gallons or "x".

    To do so, you isolate "x" in the equation:

    1.42x = 14.95 Divide 1.42 on both sides (or divide 14.95 by 1.42)

    x = 10.5 She got 10.5 gallons
