Jennie makes quilts. She can make 7 quilts with 21 yards of material. How many yards of material would be required to make 12 quilts?
Thoughts? Step-by-step reasoning:
The amount of material that Jennie needs per quilts is 21 yards / 7 quilts = 3 yards per quilt. In order to make 12 quilts, Jennie will need 12 quilts * 3 yards = 36 yards.
Thus, the answer is 36.
