A bank charges a base fee of $10 per month, plus the following check fees for a commercial checking account:
$.10 each for less than 20 checks
$.08 each for 20-39 checks
$.06 each for 40-59 checks
$.04 each for 60 or more checks
Write a program that asks for the number of checks written for the month. The program should then calculate and display the bank's service fees for the month.
