Tanesha needs to buy rope so cut into 10 pieces that are each six inches long. She sees a 6-foot length of rope that cost $5 and also sees 1-foot lengths of rope that cost $1.25 each. What is the least she has to spend to get the rope she needs? Give me reasons, before answering the question

She needs 60 inches of rope because 10 x 6 equals 60. The six - foot length of rope is 72 inches long because 6 x 12 = 72. The six - foot length of rope would give her 12 pieces because 72 / 6 = 12. The six - foot length is long enough because 12 > 10. Each 1 - foot rope equals 12 inches. She would need 5 of the 1 - foot ropes because 60 / 12 = 5. If she bought one - foot ropes it would cost $6.25 because 5 x 1.25 = 6.25. The cheapest rope to buy is the 6 - foot rope because 5 < 6.25. So the final answer is 5.
