Here is a short Python program.

```python
score = 7
cost = 3
bins = [9, 2, 6, 0]
for elem in bins:
    cost = score - 6
    cost -= 3
score += cost
score += bins[-1]
```

After this program runs, what is the value of `score`? 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 program step by step:

1. `score = 7`
2. `cost = 3`
3. `bins = [9, 2, 6, 0]`
4. The `for` loop iterates through the elements of `bins`:
   - First iteration: `elem = 9`
     - `cost = score - 6`  => `cost = 7 - 6 = 1`
     - `cost -= 3` => `cost = 1 - 3 = -2`
     - `score += cost` => `score = 7 + (-2) = 5`
   - Second iteration: `elem = 2`
     - `cost = score - 6` => `cost = 5 - 6 = -1`
     - `cost -= 3` => `cost = -1 - 3 = -4`
     - `score += cost` => `score = 5 + (-4) = 1`
   - Third iteration: `elem = 6`
     - `cost = score - 6` => `cost = 1 - 6 = -5`
     - `cost -= 3` => `cost = -5 - 3 = -8`
     - `score += cost` => `score = 1 + (-8) = -7`
   - Fourth iteration: `elem = 0`
     - `cost = score - 6` => `cost = -7 - 6 = -13`
     - `cost -= 3` => `cost = -13 - 3 = -16`
     - `score += cost` => `score = -7 + (-16) = -23`
5. `score += bins[-1]` => `score += 0` => `score = -23 + 0 = -23`

Therefore, the final value of `score` is -23.

ANSWER: -23
