🧮 Commission and Discount Recheck

Students revisit their sales model to recompute markup, discount, tax, and staff commission after the competitor enters the market. They use calculators, ratio tables, and decimal conversion notes to verify each step and flag any anomalies between projected sales and profit. Each student completes a brief oral debrief in pairs at the end: one ratio or percent strategy that worked, one mistake corrected, and one way the team stayed organized under pressure.
