A rental car agency charges $15 per day plus $.11 per mile to rent a certain car. Another agency charges $18 per day plus 8 cents per mile to rent the same car. If they rent the car for one day how many miles will they have to be driven for the cost of a car from the first agency to equal the cost of a car from the second agency.

  • Math -

    the cost is the same for m miles if

    15+.11m = 18+.08m

    Now just solve for m.

    you're all wrong, you idiots. it's 100 miles.

    15 + .11m = 18 + .08m

    .11m = 3 + .08

    .03 = 3

    m = 100
