Problema Solution
Flying on a recent trip to Las Vegas two-thirds of the planes seats were occupied.
20% of the occupied seats were boys, one-fourth of the occupied seats were
women, one-eighth of the occupied seats were girls, and 68 of the occupied seats were men.
How many seats are on the plane?
Answer provided by our tutors
let x = the total number of seats on the plane
0.20*(2/3)x + (1/4)(2/3)x + (1/8)(2/3)x + 68 = (2/3)x multiply both sides by 1/(2/3)
0.20x + 0.25x + 0.125x + 102 = x
by solving we find
x = 240 seats
there are 240 seats in the plane.
