Terry is making 4 hat and scarf sets. each scarf requires 1 yards of material and each hat requires 30 inches of material. how many feet of material does he need for all 4 hat and scarf sets?

Terry needs 22 feet of material. One yard is three feet, and he needs 4 yard-long scarves, so multiply 3 by 4, which gives you twelve. Next, figure for the hats. He needs 30 inches for 4 hats each, so multiply 30 by 4. That'll give you 120 inches. Convert the 120 inches to feet and you've got 22 feet total!
