Answer: You want to ship 80 items, and each case holds 7 items. To find the number of cases needed to ship the 80 items, you can use the formula:
Number of cases = (Number of items) / (Items per case)
So in this case, the number of cases needed to ship 80 items is:
Number of cases = 80 / 7
Which simplifies to 11.428571428571429, so you will need 12 cases to ship 80 items.
