Chapter 4, Problem 5PC

BankCharges Class

A bank charges $10 per month, plus the following check fees for a commercial checking account:

$.10 for each check if less than 20 checks were written

$.08 for each check if 20 through 39 checks were written

$.06 for each check if 40 through 59 checks were written

$.04 for each check if 60 or more checks were written

The bank also charges an extra $15 if the account balance falls below $400 (before any check fees are applied). Design a class that stores the ending balance of an account and the number of checks written. It should also have a method that returns the bank’s service fees for the month.
