1. **State the problem:** A bakery sold 58 eclairs in the morning. It sold 15 fewer eclairs in the afternoon than in the morning. We need to find how many eclairs it sold altogether. 2. **Identify the quantities:** - Morning sales = 58 eclairs - Afternoon sales = Morning sales - 15 3. **Write the expression for afternoon sales:** $$\text{Afternoon sales} = 58 - 15$$ 4. **Calculate afternoon sales:** $$58 - 15 = 43$$ 5. **Find total sales by adding morning and afternoon sales:** $$\text{Total sales} = 58 + 43$$ 6. **Calculate total sales:** $$58 + 43 = 101$$ 7. **Answer:** The bakery sold **101 eclairs** altogether. This problem uses simple subtraction to find the afternoon sales and addition to find the total sales. Always remember to subtract the smaller quantity from the larger when the problem states "fewer" and then add to find the total.
