3 answers

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

  1. 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.

wait the last one is suppose to be 12 divided by 3 x 9

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:

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

  1. 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.
