Answer:
845
Explanation:
If you make 25 correct moves, and each correct move is worth 50 points, then the total amount of points you gain from correct moves is:
25x50=1250
If you lose 3 points for every second you take, and you spent 135 seconds (2 minutes and 15 seconds), the total amount of points lost due to time is:
3x135=405
Your overall score = points gained - points lost = 1250-405 = 845
