conversations.value: Two siblings, Eman and Frank, agreed to buy a new computer table, computer chair, and a joystick. The computer table costs $140, the computer chair costs $100, and the joystick costs $20. Eman agreed to pay for the computer chair while Frank agreed to pay for the computer table. Then Frank agreed to pay 1/4 of the price of the joystick and the rest will be paid by Eman. How much more money will Frank spend than Eman?
  Give me a detailed solution.

conversations.value: Frank will pay $20 x 1/4 = $5 for the joystick.
  Eman will pay $20 - $5 = $15 for the joystick.
  So, Frank will pay a total of $140 + $5 = $145.
  While Eman will pay a total of $100 + $15 = $115.
  Therefore, Frank will spend $145 - $115 = $30 more than Eman.
