Your credit card shows a $600 debt liability. The interest rate is 24% pa, payable monthly. You can't pay any of the debt off, except in 6 months when it's your birthday and you'll receive$50 which you'll use to pay off the credit card. If that is your only repayment, how much will the credit card debt liability be one year from now?
