    The answer is A. c = 1.89n

    Step-by-step explanation:

    This is pretty straightforward:

    The cost (c) is $22.68

    The number of gallons purchased (n) is 12

    22.68 divided by 12 equals 1.89

    Therefore c = 1.89n

    What I want to know is: Where in the U. S. did Edie find gasoline for $1.89 per gallon?
