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