Therefore, 3806/22 = 173
The answer is 1/7n + 32/21
Given that Dam had $23 to spend on three pens.
After buying them he had $11.
Let x be the cost of each pen.
The given statement can be written as follows.
![23-3x=11](https://tex.z-dn.net/?f=23-3x%3D11)
Subtracting 23 from both sides, we get
![23-3x-23=11-23](https://tex.z-dn.net/?f=23-3x-23%3D11-23)
![-3x=-12](https://tex.z-dn.net/?f=-3x%3D-12)
Dividing both sides by -3, we get
![-\frac{3x}{-3}=-\frac{12}{-3}](https://tex.z-dn.net/?f=-%5Cfrac%7B3x%7D%7B-3%7D%3D-%5Cfrac%7B12%7D%7B-3%7D)
![x=4](https://tex.z-dn.net/?f=x%3D4)
Hence the cost of each pen is $4.
