Consider the question. The marching band has 110 members. There are 4 times as many percussion players as there are woodwind, and twice as many woodwinds as brass. How many brass players are there?
 If the answer is '10'; explain the reasoning:
Let x represent the number of brass players in the band. Woodwind:2x. Percussion:4(2x) = 8x. Total:x + 2x + 8x = 110. 11x = 110. x = 10.
