To represent the student's purchase of 3 notebooks and 2 (let's assume they are 2 folders), you can denote the cost of a notebook as \( x \) and the cost of a folder as \( y \).
The total cost equation can be set up as follows:
\[
3x + 2y = 9
\]
This equation indicates that the student is buying 3 notebooks (costing \( 3x \)) and 2 folders (costing \( 2y \)), with a total spending limit of $9.
