Question

 Consider the following two car rental companies. Cars R Us charges $100 up front, plus 10 cents per mile. Thrifty Car Rentals charges 25 cents per mile with no upfront fee. If TC represent the total cost for the car, and n represents the number of miles, which of the following systems of equations best represents this situation?

  1. TC = 100 + 0.10n

    TC = 0.25n

  2. TC = 100 - 0.10n

    TC = 0.25 - n

  3. TC = 100 + 0.10 / n

    TC = 0.25 / n

  4. n = 100 + 0.10 / TC

    n = 0.25 / TC

  5. n = 100 + 0.10TC

    n = 0.10 TC
