John needs 150 feet of rope to section off part of his barn. At a local hardware store he can buy a 30-yard spool for $24.00 or he can buy 150 foot at $0.25 per foot. Which is the better buy?

150 feet at $0.25 per foot

Step-by-step explanation:

You need to multiply 24/30 by 5 to get 150 yd so its 120/150. You need to multiply. 25 by 150 because you need to buy 150 feet for rope that then need to multiply again by 3 because you need to convert feet into yards. You get 112.5/150. That's less than 120/150
