Financial Algebra Second Edition
Slide 12
Solution
Finance charges are computed monthly, so the 18% APR must be divided by 12 to get a monthly percentage rate of 1.5%. Take 1.5% of the average daily balance to get the finance charge.
You can view this algebraically as a formula.
Substitute.
The finance charge is $21.62.

This activity will illustrate how even smaller purchases cost more when you purchase on a credit card and do not pay the balance in full each month. For this activity, we will use the credit card calculator from bankrate.com; open it in another window. We also make these assumptions:
● Your credit card’s interest rate (APR) is 19.9%.
● The minimum payment due each month is 3% of your starting balance.
Now, Go to Quizzes on Canvas to do the lesson’s activity:
