how do i answer this on an excel file? plz include formulas

You get a new credit card and charge $400 each month to it. You only pay the minimum balance. The minimum is the greater of $30 or 1.5% of the balance. Your credit card charges 24% annual percentage rate (APR) interest. How much do you owe at the end of two years? How much less would you owe if the APR was 15%? Set this problem up just as you did Credit Card 12. Be sure to answer the two questions and highlight them so that the grader can find them. Foc B I A E E
