A bank charges $8 per month plus the following fees:

fee Number of checks

$.09 each 1 - 20 checks

$.07 each 21 40 checks

$.06 each 41 60 checks

$.05 each More than 60 checks

If the number of checks is a negative number or 0, issue an error message and set the fee to -999. The program should ask the user for the number of checks and compute and display the fee. For example, if a person writes 10 checks, the fees displayed will be $8.9 (8 + 10*.09). If the number of checks is a negative number or 0, fee displayed will be -999.
