Lucy’s Bonus and Piecewise Functions

Vincent explains a piecewise function word problem involving Lucy's sales bonuses. Lucy earns a $25 bonus per sale for up to 20 sales and $40 for each sale beyond 20. The video guides viewers through setting up a piecewise function to model this scenario, demonstrating calculations for different sales numbers. The function is applied to determine Lucy's bonuses for August and September, illustrating the practical use of piecewise functions in real-world problems.
