A personal computer salesperson receives a base salary of $1500 per month and a commission of 5% of all sales over $10,000 during the month. If the monthly sales are $20,000 or more, then the salesperson is given an additional $500 bonus. Let E(s) represent the person's earnings per month as a function of the monthly sales s. Answer parts (a) through (d). (a) Graph E(s) for O S s $ 30,000. Choose the correct graph below. O A. B. Oc.
