Please perform below 4 steps to solve the task: 1. Read the problem statement. 2. Formulate the algorithm using pseudocode and top-down, stepwise refinement. 3. Write a C program. 4. Test, debug and execute the C program Task: One large chemical company pays its salespeople on a commission basis. The salespeople receive $200 per week plus 9% of their gross sales for that week. For example, a salesperson who sells $5000 worth of chemicals in a week receives $200 plus 9% of $5000, or a total of $650. Develop a program that will use scanf to input each salesperson's gross sales for last week and calculate and display that salesperson's earnings. Process one salesperson's figures at a time. Here is a sample input/output dialog: Enter sales in dollars (-1 to end): 5000.00 Salary is $650.00 Enter sales in dollars (-1 to end): 1234.56 Salary is $311.11 Enter sales in dollars (-1 to end): -1
