• 7. Making Payments on Credit Cards

You have had a credit card for 2 years. Use the terms and conditions below that apply to your credit card.

You have the lowest possible APR. You use the credit card to purchase 3 nights in a hotel for a total of \$350. Your bill also includes \$250 from last month. The minimum payment each month is \$15. How long does it take to pay the credit card bill by making only the minimum payment each month? How much do you pay in interest? (See Example 3 and Example 4.)

• Worked-Out Solution

This is a difficult question. The best way to answer it is to create a spreadsheet showing the effect of minimum payments. From the spreadsheet, you can see that it would take 53 months to pay the balance on the credit card.

By totaling the interest column, you can see that you would pay about \$190.54 in interest.

• 11. Comparing Interest Rates

You can pay the \$1730 credit card balance with a 2-year installment loan that has an APR of 6.5%, or a 1-year installment loan that has an APR of 9%. Which loan has a lesser cost of credit? How much do you save by choosing this loan? (See Example 3 and Example 4.)

• Worked-Out Solution

For a 24-month loan, the annual percentage rate is 6.5%. This implies that the monthly payment is

The total paid during the 2 years is

This implies that the cost of credit is

For a 12-month loan, the annual percentage rate is 9%. This implies that the monthly payment is

The total paid during the year is

This implies that the cost of credit is

So, the one year loan has the lesser cost of credit. It costs

less than the two-year loan.
