To find the change in score, we can calculate it by subtracting the original score from the final score.
Original score: -500 points
Final score: 2,700 points
Change in score = Final score - Original score
Change in score = 2,700 - (-500)
Change in score = 2,700 + 500
Change in score = 3,200 points
So, the change in score is 3,200 points.
