Here is a short Python program.

```python
spare = 2
margin = 5
step = 3
spare += margin
margin = margin + 3

def shift_by(amt):
    w = amt + 9
    return w * 2

step += 7
spare += step
```

After this program runs, what is the value of `spare`? Work through it carefully, then give the final answer on its own last line as `ANSWER: <python literal>`.

To find the final value of `spare`, let's trace the execution of the program step-by-step:

1.  **Initialization:**
    *   `spare = 2`
    *   `margin = 5`
    *   `step = 3`

2.  **First operation (`spare += margin`):**
    *   `spare = 2 + 5`
    *   `spare = 7`

3.  **Second operation (`margin = margin + 3`):**
    *   `margin = 5 + 3`
    *   `margin = 8`

4.  **Function Definition (`def shift_by(amt):`):**
    *   The function `shift_by` is defined, but it is **never called** during the execution of the script. Therefore, the code inside the function does not affect any variables.

5.  **Third operation (`step += 7`):**
    *   `step = 3 + 7`
    *   `step = 10`

6.  **Final operation (`spare += step`):**
    *   `spare = 7 + 10`
    *   `spare = 17`

The final value of `spare` is 17.
