Here is a short Python program.

```python
values = [5, 8]
cost = 7
bonus = 2
values.append(bonus)
cost = cost if cost > bonus else bonus + 3
cost += 2
values.append(cost * 2)
bonus = values[-1]
cost = bonus * 2
bonus = values[-1]
cost = len(values) // 3
cost = len(values)
bonus = len(values) % 4
cost += 7
```

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

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

1.  `values = [5, 8]`
2.  `cost = 7`
3.  `bonus = 2`
4.  `values.append(bonus)` $\rightarrow$ `values` is now `[5, 8, 2]`
5.  `cost = cost if cost > bonus else bonus + 3`
    *   `7 > 2` is True, so `cost = 7`
6.  `cost += 2` $\rightarrow$ `cost = 9`
7.  `values.append(cost * 2)`
    *   `9 * 2 = 18`
    *   `values` is now `[5, 8, 2, 18]`
8.  `bonus = values[-1]` $\rightarrow$ `bonus = 18`
9.  `cost = bonus * 2` $\rightarrow$ `cost = 36`
10. `bonus = values[-1]` $\rightarrow$ `bonus = 18`
11. `cost = len(values) // 3`
    *   `len(values)` is 4.
    *   `4 // 3 = 1` $\rightarrow$ `cost = 1`
12. `cost = len(values)` $\rightarrow$ `cost = 4`
13. `bonus = len(values) % 4`
    *   `4 % 4 = 0` $\rightarrow$ `bonus = 0`
14. `cost += 7` $\rightarrow$ `cost = 11`

Throughout the final steps, the variable `cost` and `bonus` were modified, but the list `values` was not changed after step 7.

Final state of `values`: `[5, 8, 2, 18]`
