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>`.

Let's trace the execution of the Python code step by step:

1. `spare = 2`
2. `margin = 5`
3. `step = 3`
4. `spare += margin`  => `spare = spare + margin = 2 + 5 = 7`
5. `margin = margin + 3` => `margin = 5 + 3 = 8`
6. `def shift_by(amt): ...`  (This defines a function, but doesn't execute it yet)
7. `step += 7` => `step = step + 7 = 3 + 7 = 10`
8. `spare += step` => `spare = spare + step = 7 + 10 = 17`

The final value of `spare` is 17.

ANSWER: 17
