The algorithm for calculating the commission rate for a sales person based on their volume of sales for the month uses the table below: On sales volume ($) of Commission rate (%) $0.00$200.00 5 $200.01$1000.00 8 $1000.01$2000.00 10 $2000.01 and above 12 The calculated commission is an accumulated amount according to the sales volume figure. For example, the commission for a sales volume of $1200.00 would be calculated as follows: Commission = (200 * 5%) + ((1000 200) * 8%) + ((1200 1000) * 10%)) Based on the above information, design a program that asks a user for their salesperson number, name, and their volume of sales for the month. The program should then output back to the user, their salespersons number, volume of sales, and their calculated commission. This should be a repeated program, where the user is allowed to calculate commission until they want to quit. This program must use at least 3 FUNCTIONS. The function prototypes and function definitions are completely up to you and your software design approach. Deliverables: Hierarchy Chart in Microsoft Word Program Pseudocode in Microsoft Word
