To determine the cost per muffin when three dozen muffins cost $9.00, you need to follow these steps:

1. **Understand the total quantity**: One dozen equals 12 muffins, so three dozen equals 3 x 12 = 36 muffins.

2. **Calculate the cost per muffin**: To find the cost per muffin, you divide the total cost by the total number of muffins.

The calculation would be:
\[ \text{Cost per muffin} = \frac{\text{Total cost}}{\text{Total muffins}} = \frac{9}{36} \]

3. **Simplify the division**: Calculate:
\[ \frac{9}{36} = 0.25 \]

Thus, the cost per muffin is $0.25.

From the options provided, the correct approach is:
**9 divided by (3 x 12)**, which correctly represents the calculation of $9 divided by 36 muffins.

No worries! Let's clarify the options with the correct last one being "12 divided by 3 x 9."

Here’s how we would solve for the cost per muffin:

1. **Identify total muffins in three dozen**: As established, three dozen equals \(3 \times 12 = 36\) muffins.

2. **Determine the total cost**: The total cost for three dozen muffins is $9.00.

3. **Find the cost per muffin**: We calculate this by dividing the total cost by the total number of muffins:

\[
\text{Cost per muffin} = \frac{9}{36} = 0.25
\]

4. **Check the options**:
- **9 divided by 3**: This would yield 3, not solving for cost per muffin.
- **9 divided by 12**: This would yield 0.75, which is incorrect.
- **9 divided by (3 x 12)**: Correct, since it represents \( \frac{9}{36} \).
- **9 divided by 3 x 12**: Incorrect, as the operations don't align with solving for cost per muffin.
- **12 divided by 3 x 9**: This would be calculated as \( \frac{12}{3} \times 9 = 4 \times 9 = 36\), which also doesn’t help in finding the cost.

So in conclusion, the best option to determine the cost per muffin remains **9 divided by (3 x 12)**, which gives us the cost per muffin of $0.25. The last option you mentioned doesn't lead to the cost per muffin.
