To determine the cost per muffin, we first need to know how many muffins there are in three dozen. One dozen equals twelve, so three dozen equals:
3 × 12 = 36 muffins.
Then, we take the total cost of the muffins which is $9.00 and divide that by the total number of muffins:
Cost per muffin = Total cost ÷ Number of muffins Cost per muffin = $9.00 ÷ 36
Now, let's look at the process options given:
- The correct option is 9 ÷ (3 × 12), since we are dividing the total cost by the total number of muffins.
Next, to calculate the cost per muffin: \[ Cost per muffin = 9.00 ÷ 36 = 0.25 \]
So the cost per muffin is $0.25 per muffin.
