A $50$-gon \(Q_1\) is drawn in the Cartesian plane where the sum of the \(x\)-coordinates of the \(50\) vertices equals \(150\). A constant scaling factor \(k = 1.5\) applies only to the \(x\)-coordinates of \(Q_1\). The midpoints of the sides of \(Q_1\) form a second $50$-gon, \(Q_2\), and the midpoints of the sides of \(Q_2\) form a third $50$-gon, \(Q_3\). Find the sum of the \(x\)-coordinates of the vertices of \(Q_3\).
