  Jonah bought 6 pineapples for $3 each. Each pineapple could be cut into 12 pineapple rings. He sold 4 pineapple rings for $5 each. How much profit did Jonah make?
conversations.from: assistant
conversations.value: Jonah spent 6 x $3 = $18
  He made a total of 6 x 12 = 72 pineapple rings.
  He sold 72/4 = 18 sets of pineapple rings.
  He made 18 x $5 = $90
  His profit was $90 - $18 = $72
