conversations.value: Please show me the solution for: Borris liquor store uses 90 kilograms of grapes every 6 months. He is thinking of increasing his production by twenty percent. How many grapes does he need in a year after increasing his production?
conversations.from: assistant
conversations.value: Borris uses 90 x 2 = 180 kilograms of grapes per year.
  The increase of kilograms of grapes he needed per year is 180 x 0.20 = 36.
  Therefore, Borris needs 180 + 36 = 216 kilograms of grapes in a year.
