Assume you have a credit card balance of $20,000. The annual rate on the balance is 22%. Your bank requires a monthly minimum payment of 4% of the outstanding balance or $60, whichever is higher.

A. How many months will it take to reach $60 payment minimum?

B. How many years will it take to pay off the balance if ONLY minimum required payments are made?

C. If you pay an extra $25 every month, how long will it take to pay off the original balance?

D. How much extra must you pay every month in order to pay off the balance in 5 years?
