Harold works at a resort from the beginning of March to the end of September. During the month of August this past year, he made 3 times the average (arithmetic mean) of his monthly totals in tips for the other months. His total tips for August were what fraction of his total tips for all of the months he worked?

A. 1/3

B. 2/5

C. 3/7

D. 1/2

E. 4/7

Harold works for 7 months.

If we let the average of the 6 months besides August = n, then the sum of the tips of these months is 6n.

Thus, during August he made 3n.

August’s tips, as a fraction of the total tips, is:

(3n)/(3n + 6n)

3n/9n = 1/3

Answer: A
