Final Answer:

a) For the credit card with a 20% APR and a 2-year payoff period, the monthly payment is approximately $510.34. For the credit card with a 22% APR and a 1-year payoff period, the monthly payment is approximately $921.12. b) The total amount paid since January 1 will be $12,248.16 for the 20% APR card and $11,053.44 for the 22% APR card. c) The interest percentage for the 20% APR card is approximately 22.48%, and for the 22% APR card, it is approximately 10%.

Step-by-step explanation:

a) To calculate the monthly payments, we can use the formula for monthly payments on an amortizing loan:
\[PMT = (P \cdot r \cdot (1 + r)^n)/((1 + r)^n - 1)\], where PMT is the monthly payment, P is the principal (initial balance), r is the monthly interest rate, and n is the total number of payments (months). For the 20% APR card with a 2-year payoff, the monthly payment is approximately $510.34. For the 22% APR card with a 1-year payoff, the monthly payment is approximately $921.12.

b) The total amount paid since January 1 can be calculated by multiplying the monthly payment by the total number of payments. For the 20% APR card, it is $510.34 * 24 = $12,248.16, and for the 22% APR card, it is $921.12 * 12 = $11,053.44.

c) The interest percentage is calculated by subtracting the initial balance from the total amount paid and then dividing by the initial balance. For the 20% APR card, it is approximately 22.48%, and for the 22% APR card, it is approximately 10%. These percentages represent the portion of the total payment that goes towards interest.

In summary, these calculations provide a clear understanding of the monthly payments, total amount paid, and the percentage allocated to interest for two credit cards with different APRs and payoff periods.
