conversations.value: Can you explain how to solve this math problem: Three years ago, Rosie purchased an art piece for $4000. The same art piece will be three times as much in another three years. How much money will the art piece have increased by?
conversations.from: assistant
conversations.value: If the art piece was bought at $4000, and its price in three years will be three times its buying price, it will be worth 3*$4000 = $12000 in another three years.
  The price of the art piece will increase by $12000-$4000 = $8000
