(Bonus Calculation) A financial institution provides professional services to banks and claims charges from the customers based on the number of mandays provided. Intemally, it has set a scheme to motivate and reward staff to meet and exceed targeted billable utilization and revenues by paying a bonus for each day claimed from customers in excess of a threshold target. This scheme is calculated at the end of year with a threshold target of 100 days, and the incentive payment for each billable day in excess of such threshold target is shown as follows: Days Bonus - 0 to 100 days Zero - 101 to 132 days 325 per billable day - 133 to 155 days E550 per billable day - Greater than 155 days 600 per billable day Please note that incentive payment is calculated progressively. As an example, if an employee reached total billable days of 140 in the year, his/her incentive payment is computed as follows: 1000+32325+8550=14800 Write a program that requests an employee to enter their billable days and prints the bonus he/she has obtained.
