messages.content: After the first week, the fee will be $100 * 5% = $<<100*5*.01=5>>5.
  For the second week, the finance percentage will be 5% * 2 = 10%.
  George will have to pay a fee of $100 * 10% = $<<100*10*.01=10>>10 for the second week.
  In total, George will be charged $5 + $10 = $<<5+10=15>>15 in fees.
