Let \( n \) represent the number of notebooks Alex bought. The cost of the notebooks is \( 4n \) dollars, and the supply fee is $5. The total cost is given as $29.
We can set up the equation as follows:
\[
4n + 5 = 29
\]
To solve for \( n \), first subtract 5 from both sides:
\[
4n = 29 - 5
\]
\[
4n = 24
\]
Now, divide both sides by 4:
\[
n = \frac{24}{4}
\]
\[
n = 6
\]
Thus, Alex bought **6 notebooks**.
