(c) Twelve heavy weight boxers coincidentally get on the same elevator in Great Britain. Posted on the elevator wall is a sign that givens the maximum safe combined weight of the passengers, W _{max}, in stones (1 stone = 14lb_{m} ≈ 6kg). If you were one of the boxers, estimate the lowest value of W _{max} for which you would feel comfortable remaining on the elevator.
