    (a) If we let x be the number of miles and y be the total cost, the equation for relating the number of miles and the total cost would be,

    y = 0.4x + 48

    (b) If the rental cost is 60,

    60 = 0.4x + 48

    The value of x from the equation is 30.

    (c) You may prepare the table of values by allowing x be any number and then solve for y until we arrive with an answer for y being equal to 60.
