Amir bought a comic book for $9 and four pens. He spent a total of $25.(1 point)

Question

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

$$p+=

How much does each pen cost?

Answer 1

To find the cost of each pen, we can start by writing an equation based on the information provided.

Amir bought a comic book for $9 and four pens. He spent a total of $25. We can express this mathematically as:

\[ 9 + 4p = 25 \]

Where:

• \(9\) is the cost of the comic book,
• \(4p\) is the total cost of the four pens (with \(p\) being the cost of each pen).

Now, we can solve the equation for \(p\).

1. Subtract 9 from both sides: \[ 4p = 25 - 9 \] \[ 4p = 16 \]

2. Divide both sides by 4: \[ p = \frac{16}{4} \] \[ p = 4 \]

Therefore, the cost of each pen is $4.
