Assess students' ability to analyze how supply, demand, pricing, and promotion affect sales outcomes at a school bake sale. Tasks will include interpreting simple tables/graphs, calculating revenue and leftover inventory, predicting effects of price changes and promotional tactics on demand, evaluating trade-offs (e.g., lower price vs. higher volume), and making evidence-based recommendations for pricing and promotion in given scenarios. Questions may require short calculations and written explanations appropriate for grades 6–8.
