Answer: They had 24 items for the sale.
Explanation:
Given: In baking sale,
18 different people made 2 dozen items for the sale.
We know that,
1 dozen = 12 items
2 dozens = 2 x 12 items
i.e. 2 dozens = 24 items
Therefore, they will have 24 items for sales if they made 2 dozens items.
Hence, they had 24 items for the sale.
