conversations.value: Sasha heard that planting trees helps to reduce the local temperature. For each tree planted, the temperature drops .1 degree. A tree costs $6 to plant. If she got the local temperature to drop from 80 to 78.2, how much did it cost to plant the trees?
conversations.from: assistant
conversations.value: The temperature dropped 1.8 degrees because 80 -78.2 = 1.8
  She planted 18 trees because 1.8 / .1 = 18
  It cost $108 to plant the trees because 18 x 6 = 108
