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.

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**.
\[
9 + 4p = 25
\]
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**.
