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) (b) Find lim E(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. S-+10,000 A. lim E(s) = 1500 S-+10,000 O B. The limit lim E(s) does not exist. s- 10,000 Find E(10,000). E(10,000) = $ 1500 (c) Find lim E(s). Select the correct choice below and, if necessary, fill in the answer box to complete your choice. s-20,000 O A. lim E(s) = s-20,000 O B. The limit lim E(s) does not exist. S-20,000
