There are many problems throughout the text labeled IN YOUR OWN WORDS. Just relax; do not be afraid
to give your opinion. For the most part, these questions do not have "right" or "wrong" answers.
You should spend about five minutes in answering each of these questions.
These problems are designed to help you estimate financial problems, particularly in regards to credit
cards. Don't be afraid to guess, check, and then revise, if necessary.
Use the formula I = Prt as shown in Example 6.
Use the formula I = Prt. For the previous balance method, P is the
previous balance; for the adjusted balance method, P is the adjusted balance.
For the average daily balance, P is the average daily balance; see Example 7.
See Example 2.
See Example 1 for the monthly payment, and Example 3 for the APR.
See Example 1 for the monthly payment in parts a and b. Use that information

On the other hand, the problems designated "Problem Solving"
generally require techniques that do not have textbook examples.
