Write an equation that can be used to find the cost of each pen, p.

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.
