For the positive integers x, x + 2, x + 4, x + 7, and x + 27, the mean is how much greater than the median?	Answers
A) 0
B) 1
C) 2
D) 4
E) 7

Rationale: "mean = ( x + x + 2 + x + 4 + x + 7 + x + 27 ) / 5 = ( 5 x + 40 ) / 5 = x + 8 median = x + 4 thus mean - median = x + 8 - ( x + 4 ) = 4 answer = d"
Answer: D
