To find the cost of each pen, we can create the following equation based on the information provided:

Amir bought a comic book for $9 and four pens. The total amount he spent is $25.

We can express this as:

\[
9 + 4p = 25
\]

Where \( p \) represents the cost of each pen.
how much does each pen cost?

To find the cost of each pen, \( p \), we can solve the equation we established earlier:

\[
9 + 4p = 25
\]

First, we will isolate the term with \( p \) by subtracting 9 from both sides:

\[
4p = 25 - 9
\]
\[
4p = 16
\]

Next, divide both sides by 4 to solve for \( p \):

\[
p = \frac{16}{4}
\]
\[
p = 4
\]

Therefore, each pen costs **$4**.
