Question

There are 15 fewer than three times as many marching band members as there are color guard members. There are 105 members of the marching band. How many members are in the color guard?

A. 7
B. 30
C. 40
D. 60

Answer 1

x = the number of people in the color guard
3x - 15 = 105
3x = 105 + 15
3x = 120
x = 40
there are 40 people in the color guard :)
