Answer:
C: Nick's final score is 85 points.
Step-by-step explanation:
Nick initially scores 90 points on his first turn. On the next, he lost 15 points and lost 10 more. 15 plus 10 would be 25; when subtracted from 90, the difference is 65. On his final turn, he scores 20 points. When added to the current score of 65, the sum is 85 points. Nick's final score is 85 points.
