Please refer to the graphs. If the rates of change of the \(1\) to \(9\) cigarettes per day percentage and the \(10\) to \(19\) cigarettes per day percentage remain constant from \(2012\) onwards, approximately when will the \(1\) to \(9\) percentage overtake the \(10\) to \(19\) percentage? (Assume year \(2000\) is the initial year).
