  1. 8gal/340mi * $4.00/gal = $0.0941/mi
    7gal/350mi * $4.00/gal = $0.0800/mi

  2. 340/8 = 42.5 mpg

    350/7 = 50 mpg

    Take it from there.

  5. The answer is 0.01. because
    (4) (8)=32 dollar
    (32) (1/340)=0.09
    And
    (4) (7)=28 dollar
    (28) (1/350)=0.08

    0.09
    - 0.08
    --------------------
    0.01
    So the answer is 0.01 dollar
