conversations.value: Explain how to solve this math problem: Chip has a $50.00 balance on his credit card.  Since he didn't pay it off, he will be charged a 20% interest fee.  He puts $20.00 on his credit card the following month and doesn't make any payments to his debt.  He is hit with another 20% interest fee.  What's the current balance on his credit card?

conversations.value: He has a balance of $50.00 and is charged 20% interest so that's 50*.20 = $10.00
  He had a balance of $50.00 and now has a $10.00 interest fee making his balance 50+10 = $60.00
  His balance is $60.00 and he puts another $20.00 on his card for a total of 60+20 = $80.00
  He didn't make a payment that month and is hit with another 20% interest fee so that's 80*.20 = $16.00 in interest
  His new balance is 80+16 = $96.00
