This resource focuses on calculating gross weekly pay in commission-based roles by adding base salaries to percentage-based commissions. It introduces a formula for gross income: Gross Pay = Base Salary + (Total Sales × Commission Rate). The material includes a worked example involving Leo, who earns a fixed base salary plus commission from sales. Students engage in guided practice by calculating Leo's pay after selling a truck and, later, independent practice by determining his total weekly earnings from multiple sales. The resource encourages reflection on career choices considering the potential risks and biases that may affect decision-making, as well as a challenge task related to promotions and new commission rates. It aims not only to develop mathematical skills but also critical thinking regarding career prospects.
