URGENT HELP, THANKS



4) If Jill scores Y points in the first inning, and then increases her score by 1 point in each of the remaining innings, how many points in total will she score? Note that the score goes up by an additional 1 point for each inning. Plug in y = 15 to verify that you get the same answer as #1. Show the work to verify.



(note that the answer to question #1 was 54) (also, there 9 innings)
