Scott's average (arithmetic mean) golf score on his first four rounds was 68.What score does he need on his fifth round to drop his average score by 2 points?
Options:
(A) 58
(B) 72
(C) 78
(D) 88
(E) 312 Think first, then make a decision. Some random thoughts:
Average score for first 4 rounds = 68
Average score after 5 rounds = 66
Score Scott needs on his 5th round to drop average score by 2 points = 68 - (2*5) = 58 So the answer is (A).
