At an archery competition, archers get 7 points for each arrow that lands in the bull’s-eye and 4 points for each arrow that land in the ring surrounding the bull’s-eye. No points are awarded for arrows that miss both of these areas. During the competition, Kelly had 41 arrows land in either the bull’s-eye or the ring surrounding the bull’s-eye. She scored a total of 206 points. To represent her performance, she wrote the system of linear equations shown below. x + y = 41, 4x +7y = 206. What does the y-variable represent in Kelly’s system of linear equations?
