1. Stating the problem. Anna made a profit of 1200, saved 600, and shared the rest equally between her two daughters. How much did each receive? 2. Formula and rules. We use subtraction to find the remaining amount: $$R = T - S$$ We then divide the remaining amount equally: $$E = \frac{R}{2}$$ Important rule: subtract before dividing when the saved amount is removed first. 3. Calculation (intermediate work). Compute the remaining amount: $$R = 1200 - 600 = 600$$ Now divide equally between two daughters: $$E = \frac{600}{2}$$ Show cancellation when simplifying the fraction: $$= \frac{\cancel{2}\cdot 300}{\cancel{2}} = 300$$ 4. Conclusion. Each daughter receives $300$.
