Question

In the high school band there are 2 percussionists on the sideline to every 13 marching instruments. If the high school band has 150 total members, then how many percussionists are on the sideline?

Answer 1

180 / (13 + 2) =12 bands of 15 students each.

Since 2 from each band are sidelined, then:

12 x 2 = 24 - number of students on the sidelines, so that:

13 x 12 + 24 =180 - total number of students.
