To find out the number of boxes needed to ship off all 492 shirts, we can divide the total number of shirts by the number of shirts per box.
The number of shirts per box is given as 24.
So, to calculate the number of boxes needed, we can use the formula:
Number of boxes = Total number of shirts / Number of shirts per box.
Replacing the values, we have:
Number of boxes = 492 shirts / 24 shirts per box.
Now, let's do the calculation:
Number of boxes = 20.5 boxes.
Since you cannot have half of a box, the company will need to round up to the nearest whole number. Therefore, it will take 21 boxes to ship off all 492 shirts.
