At the Red Sox/ Yankees game on Monday night, 65% of the fans were men (adult male). Another 25% were women (adult female). Of the remainder, 40% were boys and the rest were girls. If 640 boys attended the game, what was total number of people in attendance?
65% + 25 % = 90 %
the remainder is 10% of which 40% were boys
x = fans in attendance
.10 x * .40 = 640
x = 640 / (.1*.4) = 16 000 in attendance
