Charisa Williams is the sales manager of an online financial data service company that specializes in providing brokerage firms and independent financial analysts with up-to-date financial market data and analysis. She keeps track of the commissions of her salespeople to make sure that their earnings are competitive with those of other firms. The Commissions spreadsheet has the sales of her team in January. She expects the sales amount to increase by 5% each month for the senior sales representatives and 3% for the junior sales representatives. The base monthly salaries are $3,000 and $2,000 for senior and junior sales representatives, respectively. The sales commission rate is 8% and 6% for senior and junior sales representatives, respectively. If the monthly sales of a sales representative exceeds $100,000, he or she receives a 5% bonus on the commission of that month. The personal marginal income tax rates are 15% for up to $1,999, 22% for up to $4,999, 27% for up to $9,999, and 30% for anything beyond $9,999. a.
