Answer 1

Notebook: 5$ each. Folder: 7.50$ each.

Explanation:

A notebook costs 5$ more than a folder, and 3 notebooks were purchased, so we can safely say that at least 15$ was spent on notebooks. Then, take the remaining number after subtracting 15 from 30 and divide it by 2, assuming all of the folders are the same price.
