# Mathematical Problem

Suppose that $R, S$ and $T$ are digits and that $N$ is the four-digit positive integer $8 R S T$. That is, $N$ has thousands digit 8, hundreds digit $R$, tens digits $S$, and ones (units) digit $T$, which means that $N=8000+100 R+10 S+T$. Suppose that the following conditions are all true: - The two-digit integer $8 R$ is divisible by 3. - The three-digit integer $8 R S$ is divisible by 4. - The four-digit integer $8 R S T$ is divisible by 5. - The digits of $N$ are not necessarily all different. What is the number of possible values for the integer $N$?

## Instructions

Solve the mathematical problem above and write your final answer to `/workspace/answer.txt`.

**Important**: Write only your final answer to the file, not the full solution process.

### Guidelines

- Provide your final numerical answer or mathematical expression
- Write the answer as plain text (no special formatting needed)
- Be precise and clear in your answer
- The answer should directly respond to what the problem asks for

### Example

If the problem asks "What is 2 + 2?", your answer file should contain:

```
4
```

Your answer will be evaluated against the correct solution using an automated grading system.
