Question
**Code Tracing Explanation**

The task is to trace the given Python code with specified inputs. The program calculates the miles per gallon (mpg) of a vehicle using the provided mileage and fuel data.

### Python Code
```python
starting_milage = int(input('Enter the starting milage: '))
ending_milage = int(input('Enter the ending milage: '))
gallons = float(input('Enter the gallons: '))
mpg = (ending_milage - starting_milage) / gallons
print('The miles per gallon is %0.2f' % mpg)
```

### Inputs
- **Starting Mileage:** 5000
- **Ending Mileage:** 5450
- **Gallons:** 20

### Code Execution Steps
1. The user inputs a starting mileage of 5000.
2. Next, an ending mileage of 5450 is entered.
3. The user inputs 20 gallons of fuel consumed.
4. The program calculates miles per gallon (mpg) as follows:
   \[
   \text{mpg} = \frac{\text{ending\_milage} - \text{starting\_milage}}{\text{gallons}} = \frac{5450 - 5000}{20} = \frac{450}{20} = 22.5
   \]
5. The script then prints the output: "The miles per gallon is 22.50".

### Tabular Representation of Code Trace
The table shows the step-by-step calculations and output:

| starting_milage | ending_milage | gallons | mpg  | output                         |
|-----------------|---------------|---------|------|--------------------------------|
| 5000            | 5450          | 20      | 22.5 | The miles per gallon is 22.50  |

This clear breakdown helps in understanding the flow of the program and the calculations involved in determining the vehicle's fuel efficiency.
