Q:
# Mary and Amy had a total of 20 yards of material from which to make costumes. Mary used three times more material to make her costume than Amy used, and 2 yards of material was not used. How many yards of material did Amy use for her costume?

Accepted Solution

A:

Let x be the amount Amy used

Let 3x be the amount Mary used

Let 20-2 be the total amount used

3x + x = 20-2

4x=18

x=4.5

Amy use 4.5 yards of material.
