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 input each salesperson's gross sales for last week and will 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
