Q: Scott's average (arithmetic mean) golf score on his first four rounds was 28.What score does he need on his fifth round to drop his average score by 2 points?
Options:
(A) 18
(B) 72
(C) 78
(D) 88
(E) 312 Let's give some random thoughts before answering.
Average score for first 4 rounds = 28
Average score after 5 rounds = 26
Score Scott needs on his 5th round to drop average score by 2 points = 28 - (2*5) = 18
Therefore, the answer is (A).
