Antonio works for a car dealership. He's paid a base salary plus a commission for each car he sells. One year Antonio sold 10 cars and made $35,000. Another year he sold 13 cars and made $39,500. Gee, Antonio. Only 23 cars in two whole years? What are you doing, being nice and non-aggressive toward your customers? What kind of a car salesman are you?
What is Antonio's base salary, and what is his per-car commission?
