1. **State the problem:** We are given a total amount of 103,900 and an income of 112,000. We need to find the amount the family will have left for other expenses or emergencies. 2. **Formula used:** To find the leftover amount, subtract the total amount spent from the income. $$\text{Leftover} = \text{Income} - \text{Total Amount}$$ 3. **Substitute the values:** $$\text{Leftover} = 112,000 - 103,900$$ 4. **Calculate:** $$\text{Leftover} = 8,100$$ 5. **Interpretation:** The family will have 8,100 left for other expenses or emergencies after covering the total amount of 103,900.
