Melanie has 84 muffins, which he needs to box up, 9 of which are blueberry, into dozens. How many boxes does she need?
84/12 = ?
To determine the number of boxes Melanie needs, we need to consider the total number of muffins and the number of muffins in each box.
First, let's calculate the number of blueberry muffins:
Since Melanie has 84 muffins in total and 9 of them are blueberry, the remaining muffins must be of a different variety. Therefore, the number of blueberry muffins can be calculated by subtracting the remaining muffins from the total: 84 - (84 - 9) = 9.
Next, let's calculate the number of dozens needed for the blueberry muffins:
Since a dozen consists of 12 muffins, we can find the number of dozens needed for the blueberry muffins by dividing the number of blueberry muffins by 12: 9 blueberry muffins ÷ 12 = 0.75 dozens.
Now, let's find the number of dozens needed for the remaining muffins:
The number of remaining muffins can be calculated by subtracting the number of blueberry muffins from the total muffins: 84 - 9 = 75 remaining muffins.
To find the number of dozens needed for the remaining muffins, we divide this number by 12: 75 remaining muffins ÷ 12 = 6.25 dozens.
Finally, let's calculate the total number of dozens needed:
We add the number of dozens needed for the blueberry muffins (0.75 dozens) and the number of dozens needed for the remaining muffins (6.25 dozens): 0.75 dozens + 6.25 dozens = 7 dozens.
Therefore, Melanie needs 7 boxes to box up the 84 muffins, with 9 of them being blueberry.
