Question

The parents of the members of a marching band are making uniforms for the band. If a shirt
requires 2 1/4 yards of material and the pants require 2 1/2 yards of material. How much material
must the parents buy in order to outfit all 24 members of the band?

1. Using proportions, it is found that the parents must buy 114 yards of material in order to outfit all 24 members of the band.

### What is a proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
In this problem, the amounts needed for each member are given by:
• 2 1/4 yards for the shirt = 2.25 yards for the shirt.
• 2 1/2 yards for the pant = 2.5 yards for the shirt.
Hence 2.25 + 2.5 = 4.75 yards of material.
For the 24 members, the total amount is:
24 x 4.75 = 114.
114 yards of material in order to outfit all 24 members of the band.
