A $150$-gon $Q_1$ is drawn in the Cartesian plane. The sum of the $x$-coordinates of the $150$ vertices equals $3000$. The midpoints of the sides of $Q_1$ form a second $150$-gon, $Q_2$. The midpoints of the sides of $Q_2$ form a third $150$-gon, $Q_3$. Finally, the midpoints of the sides of $Q_3$ form a fourth $150$-gon, $Q_4$. Find the sum of the $x$-coordinates of the vertices of $Q_4$.
