    Answer:

    750 miles

    Step-by-step explanation:

    Ronald

    Rental fee = fixed cost + variable cost

    = $25 + $0.05x

    Where x = number of miles

    Dixon

    Rental fee = fixed cost + variable cost

    = $40 + $0.03x

    How many miles must they both drive for their rental fees to be the same?

    Equate the two equations

    $25 + $0.05x = $40 + $0.03x

    Collect like terms

    0.05x – 0.03x = 40 – 25

    0.02x = 15

    Divide both sides by 0.02

    x = 15 / 0.02

    = 750 miles
