conversations.value: Nate is feeding his livestock hay. Each goat needs 5 pounds, and each sheep needs 3 pounds less than twice the amount each goat needs. If there are 15 goats and 12 sheep, how many pounds of hay does Nate need?
conversations.from: assistant
conversations.value: First figure out how much hay each sheep needs: 5 pounds * 2 - 3 = 7 pounds/sheep
  Now figure out how much hay total the sheep need: 7 pounds/sheep * 12 sheep = 84 pounds
  Now figure out how much hay total the goats need: 5 pounds/goat * 15 goats = 75 pounds
  Now add the two amounts of hay to find the total: 84 pounds + 75 pounds = 159 pounds
