conversations.value: Explain how to solve this math problem: 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?
conversations.from: assistant
conversations.value: 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
