A company awards its salespeople 3% commission on sales below $20,000, 3.5% commission on sales from $20,000 to $30,00, and 4% commission for sales over $30,000.

To express the commission structure as a piecewise function \( f(x) \), we need to consider both the commission rates and the ranges of sales amounts correctly.
The commission rates are:
3% for sales below $20,000
3.5% for sales from $20,000 to $30,000
4% for sales over $30,000
The correct piecewise function representing the commission \( f(x) \) is:
