A personal-computer salesperson receives a base salary of \( \$ 991 \) per month and a commission of \( 5.1 \% \) 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 \( \$ 679 \). Let \( E(s) \) represent the person's earnings per month as a function of monthly sales. Consider the following values. 1. \( E(10000) \) 2. \( \lim _{s \rightarrow 10000} E(s) \) 3. \( E(20000) \) 4. \( \lim _{s \rightarrow 20000} E(s) \) Compute 3. Round to the nearest cent.
