Answer:
during the first month, Angie will pay $4.50 in interests and $5.50 in principal
I prepared an amortization table using an excel spreadsheet to determine the number of years it takes to pay off the debt balance.
At the end of the 40th month, her balance will only be $1.53. So the 41st month should be the last month that she pays and her payment should only be $1.55 to payoff her debt completely.
