12. You are purchasing a car for $12,465.00 plus 5.65% sales tax. You make a $1,300.00 down payment and have a fair credit score. How much interest is due at the end of the first month? 63.30



13. If you improved your credit score to good and paid $1,500 on your purchase from question 12, how much interest could you save in the first month? 14.68



14. You have a credit card that has a balance of $3,489.90 and a credit limit of $5,000. How much is the balance over the acceptable debt ratio percentage? 69.7%

12. The interest due will be
  I = Prt = (1.0565·$12,465.00-1300.00)·0.064·(1/12) = $63.30 . . . . correct

13. The interest due will be
  I = Prt = (1.0565·$12,465.00-1500.00)·0.05·(1/12) = $48.62
