Here is a short Python program.

```python
tally = 4
width = 2
credit = 3
tally += width
width = credit * 2
tally += credit * 2
credit = tally if tally > width else width + 9
width = width * 2
width = width - 9
credit = tally * 2
if width > credit:
    width -= width
    credit = credit * 2
else:
    credit = width * 3
    credit = credit * 2
if width < 6:
    width -= tally
    credit = tally + 4
else:
    width = tally * 2
    credit += credit
width -= width
width -= width
```

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

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

1.  `tally = 4`
2.  `width = 2`
3.  `credit = 3`
4.  `tally += width` $\rightarrow$ `tally = 4 + 2 = 6`
5.  `width = credit * 2` $\rightarrow$ `width = 3 * 2 = 6`
6.  `tally += credit * 2` $\rightarrow$ `tally = 6 + (3 * 2) = 6 + 6 = 12`
7.  `credit = tally if tally > width else width + 9`
    *   Is `12 > 6`? Yes.
    *   `credit = 12`
8.  `width = width * 2` $\rightarrow$ `width = 6 * 2 = 12`
9.  `width = width - 9` $\rightarrow$ `width = 12 - 9 = 3`
10. `credit = tally * 2` $\rightarrow$ `credit = 12 * 2 = 24`
11. `if width > credit:`
    *   Is `3 > 24`? No.
    *   Execute `else` block:
        *   `credit = width * 3` $\rightarrow$ `credit = 3 * 3 = 9`
        *   `credit = credit * 2` $\rightarrow$ `credit = 9 * 2 = 18`
12. `if width < 6:`
    *   Is `3 < 6`? Yes.
    *   Execute `if` block:
        *   `width -= tally` $\rightarrow$ `width = 3 - 12 = -9`
        *   `credit = tally + 4` $\rightarrow$ `credit = 12 + 4 = 16`
13. `width -= width` $\rightarrow$ `width = -9 - (-9) = 0`
14. `width -= width` $\rightarrow$ `width = 0 - 0 = 0`

Throughout the execution, the variable `tally` was modified only in steps 4 and 6.
*   Initial: 4
*   Step 4: 6
*   Step 6: 12

No further operations modified `tally`.
