conversations.value: Can you guide me through solving this problem: Tammy has 10 orange trees from which she can pick 12 oranges each day. Tammy sells 6-packs of oranges for $2. How much money will Tammy have earned after 3 weeks if she sells all her oranges?
conversations.from: assistant
conversations.value: Tammy picks 10 trees x 12 oranges/tree = 120 oranges per day.
  Tammy sells 120 oranges/day / 6 oranges/pack = 20 6-packs of oranges a day
  Tammy sells 20 packs/day x 7 days/week = 140 6-packs a week
  In 3 weeks Tammy sells 140 packs/week x 3 weeks = 420 6 -packs
  Tammy makes 420 packs x $2/pack = $840
