conversations.value: When the price of the bag of marble increase by 20%, the price increases by 20/100*20 = $4
  If the price increases after every two months, in 36 months, it will increase 36/2 = 18 times.
  If each increase is $4, the total amount the price of the bag of marbles will have increased by after 36 months is 18*$4 = $72
  After the total increase of the price of the bag of marbles after 36 months, the total cost will be $20+$72 = $92
