Test students' ability to plan a simple budget and pricing strategy for a lemonade stand: identify and list costs (ingredients, cups, signage), estimate quantities, calculate total and per-cup cost, set a selling price to reach a target profit, compute profit and break-even point, and adjust price based on basic demand or competition. Problems require applying grade 3–5 arithmetic (addition, subtraction, multiplication, division) and short written reasoning to justify pricing decisions.
