A total of 22 men and 26 women were at a party, and the average (arithmetic mean) age of all of the adults at the party was exactly 35 years. If the average age of the men was exactly 38 years, which of the following was closest to the average age, in years, of the women?
(A) 31
(B) 31.5
(C) 32
(D) 32.5
(E) 33
(A) 31
(B) 31.5
(C) 32
(D) 32.5
(E) 33
\((22+26)35 = 22*38 + 26w\)
So, \(1680 = 836 + 26w\)
Or, \(844 = 26w\)
Or, \(w ≅ 32.5\), Answer must be (D)
