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

$.10 per check for less than 10 checks $.08 per check for 1029 checks $.06 per check for 3049 checks $.04 per check for 50 or more checks

Write a program that asks the user for the number of checks written for the month. The program should then calculate and display the bank's service fees for the month. Format the service fee to two decimal places.
