Jerome bought 15 videos from a department store. Some videos were new releases, x, which cost $19, and some videos were classics, y, which cost $8. He spent a total of $164 on the videos. Which system of equations is set up correctly to model this information? x + y = 15. 19 x + 8 y = 164. x + y = 15. 8 x + 19 y = 164. x + y = 164. 19 x + 8 y = 15. x + y = 15. 19 x minus 8 y = 164.
