Here is a short Python program.

```python
cost = 9
offset = 4
values = [2, 9, 6, 5]
cost += offset
cost += len(values)
values[-1] = cost
```

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>`.

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

1. `cost = 9`: The variable `cost` is initialized to 9.
2. `offset = 4`: The variable `offset` is initialized to 4.
3. `values = [2, 9, 6, 5]`: The list `values` is initialized to `[2, 9, 6, 5]`.
4. `cost += offset`: This is equivalent to `cost = cost + offset`. So, `cost = 9 + 4 = 13`.
5. `cost += len(values)`: `len(values)` is the length of the `values` list, which is 4. So, `cost = cost + 4 = 13 + 4 = 17`.
6. `values[-1] = cost`: This assigns the value of `cost` (which is 17) to the last element of the `values` list. So, `values` becomes `[2, 9, 6, 17]`.

The final value of `cost` is 17.
