Here is a short Python program.

```python
cost = 2
level = 7
size = 5
if size > level:
    cost += level
    size = cost + 5
if level >= cost:
    level = cost if cost < size else size + 4
    size = size if size > level else level + 1
level += 7

def scale(val, bag=5):
    return val * 2 - bag

parts = [1, 1]
batch = parts
batch += [17]
cost += len(parts) + parts[-1]
level = scale(level)
cost += size
size = size - 7
if level < 1:
    size = cost * 3
size = size * 2
```

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

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

1.  **Initial values:**
    `cost = 2`
    `level = 7`
    `size = 5`

2.  **First `if` block:**
    `if size > level:` (5 > 7) is **False**.
    The block is skipped.

3.  **Second `if` block:**
    `if level >= cost:` (7 >= 2) is **True**.
    - `level = cost if cost < size else size + 4`
      Is `cost < size`? (2 < 5) is **True**.
      So, `level = cost` $\rightarrow$ `level = 2`.
    - `size = size if size > level else level + 1`
      Is `size > level`? (5 > 2) is **True**.
      So, `size = size` $\rightarrow$ `size = 5`.

4.  **Update `level`:**
    `level += 7` $\rightarrow$ `level = 2 + 7 = 9`.

5.  **Function definition:**
    `scale(val, bag=5)` is defined.

6.  **List operations:**
    `parts = [1, 1]`
    `batch = parts` (Both point to the same list object)
    `batch += [17]` $\rightarrow$ `parts` is now `[1, 1, 17]`.

7.  **Update `cost`:**
    `cost += len(parts) + parts[-1]`
    `len(parts)` is 3.
    `parts[-1]` is 17.
    `cost = 2 + 3 + 17 = 22`.

8.  **Update `level`:**
    `level = scale(level)` $\rightarrow$ `scale(9, 5)`
    `9 * 2 - 5 = 18 - 5 = 13`.
    `level = 13`.

9.  **Update `cost` again:**
    `cost += size`
    `cost = 22 + 5 = 27`.

10. **Update `size`:**
    `size = size - 7` $\rightarrow$ `5 - 7 = -2`.

11. **Final `if` block:**
    `if level < 1:` (13 < 1) is **False**.
    The block is skipped.

12. **Final `size` update:**
    `size = size * 2` $\rightarrow$ `-2 * 2 = -4`.

The final value of `cost` is 27.
