Evaluate strategies for managing a weekly allowance to afford a $40 toy in six months while still buying weekly treats and occasionally donating. Test skills in calculating required weekly savings (about 26 weeks), applying a small monthly interest to saved amounts, factoring occasional store discounts, modeling at least three spending plans (e.g., save more, reduce treats, give less), comparing outcomes numerically, identifying trade-offs, and justifying a recommended plan that meets the goal and aligns with values.
