(use python) A large company pays its salespeople on a commission basis. The salespeople each receive $200 per week plus 9% of their gross sales for that week if s/he sells more than 1000 a week, otherwise they get only $100 per week plus 10% of their groos 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. Write a function called CalculatingCommission that recieves one parameter which is the salesman weekly sale and then it calculates and returns the amount of the commission.
