Anthony sells cars. Each month, he is paid $2,000, plus a 15% commission on monthly sales above $20,000. Which function calculates his monthly earnings (E) as a function of m, his monthly sales?

Anthony earns a base salary of $2,000, plus commission only on the portion of sales above $20,000. That portion is m − 20,000, and 15% written as a decimal is 0.15. So his earnings are E(m) = 2,000 + 0.15(m − 20,000), which is choice A.
