Your Thanksgiving ski vacation was great, but unfortunately it ran a bit over budget.

All is not lost. You just received an offer in the mail to transfer your $9,000 balance from your present credit card that charges you an annual rate of 21.6 percent to a new credit card charging a rate of 9.0 percent.

b.What is the total amount of interest you will pay on the $9000 balance if you repay it at $200 per month at your original 21.6 percent interest rate?

c.c. If you want to pay off your entire $9,000 balance within one year, at the 9.0 percent APR, what must your monthly payment be?
