(4) Creditworthiness is measured by a "credit score," with a high credit score indicating good credit. In the following questions, you will explore how your credit score can affect how much you have to pay in order to borrow money. Juanita and Brian both have a credit card with the terms in the disclosure form given above. They have both had their credit cards for more than 6 months. (a) Juanita has good credit and gets the lowest interest rate possible for this card. She is not able to pay off her balance each month, so she pays interest. Estimate how much interest Juanita would pay in the month of January if her unpaid balance is $5000. Explain your estimation strategy. (b) If Juanita maintains an average balance of $5000 every month for a year, estimate how much interest she will pay in a year. Explain your estimation strategy. (c) Brian has a very low credit score and has to pay the highest interest rate. He is not able to pay off his balance each month, so he pays interest. Calculate how much interest he would pay in the month of January if his balance is $5000
