1. **State the problem:** We need to find the fuel mileage, which is the number of miles driven per gallon of fuel used. 2. **Formula:** Fuel mileage (miles per gallon) is calculated as: $$\text{Fuel mileage} = \frac{\text{Miles driven}}{\text{Gallons used}}$$ 3. **Substitute the values:** $$\text{Fuel mileage} = \frac{225}{8.03}$$ 4. **Calculate the division:** $$\text{Fuel mileage} = 28.01$$ 5. **Interpretation:** This means you get approximately 28.01 miles per gallon of fuel. **Final answer:** $$\boxed{28.01 \text{ miles per gallon}}$$
