conversations.value: Can you walk me through the solution of: Hendricks buys a guitar for $200, which is 20% less than what Gerald bought the same guitar for. How much did Gerald pay for his guitar?
conversations.from: assistant
conversations.value: Let G be the price Gerald paid for his guitar.
  Then 0.8 * G = $200
  So G = $200 / 0.8 = $250
