This learning resource focuses on teaching students how to translate word problems into multi-variable algebraic expressions and evaluate these expressions to calculate costs related to a school store budget. The document contains a variety of activities designed to help students practice writing expressions, matching descriptions with algebraic expressions, substituting values into expressions, and evaluating total costs. Activities include writing expressions for different bundles of items, substituting values to find costs, identifying errors in calculations, and creating tiered pricing models. The culmination of these exercises is a challenge that requires students to formulate a budget plan using multi-variable inequalities to maximize their purchases within a specified budget.
