Chapter 8.8, Problem 4E
In Exercises 3-4 involve credit cards that calculate interest using the average daily balance method. The monthly inetest rate is 1.2% of the average daily balance. Each exercise shows transactions that occurred during the June 1-June 30 billing period. In each exercises,
a. Find the average daily balance for the billing period. Round to the nearest cent.
b. Find the interest to be paid on July 1, the next billing date. Round to the nearest cent.
c. Find the balance due on July 1.
d. this credit card requires a $30 minimum monthly payment if the balance due at the end of the billing period is less than $400. Otherwise, the minimum monthly payment is $$ of the balance due at the end of the billing period, rounded up to the nearest whole dollar. What is the minimum monthly payment due by July 9?
| Transaction Description | Transaction Amount |
| Previous balance, $4037.93 | |
| June 1 Billing date | |
| June 5 Payment | $ 350.00 credit |
| June 10 Charge: Gas | $ 31.17 |
| June 15 Charge: Prescriptions | $ 42.50 |
| June 22 Charge: Gas | $ 43.86 |
| Charge: Groceries | $ 112.91 |
| June 29 Charge: Clothing | $ 96.73 |
| June 30 End of billing period | |
| Payment Due Date: July 9 |
