In order to determine how many of each type of book Santiago bought, we need additional information about the different types of books he purchased. For example:
- How many types of books are there?
- How many of each type did he intend to buy?
- Are there any constraints or conditions regarding the types of books?
Without this specific information, we can't accurately conclude the distribution of the books Santiago bought. If you provide more details, I would be happy to help you solve it!
