Answer:
60 items.
Step-by-step explanation:
The number of items sold on the first day = 16
The number of the items sold on the second day = 28
The number of the items sold on the last day = 12
The number of the items that had not been purchased = 4
Total items were for sale = 16 + 28 + 12 + 4
= 60 items
Total 60 items were for sale at the bake sale.
