Murray has a total of 8 pencils and 2 pencil pouches. To find out how many pencils are in each pouch, you can divide the total number of pencils by the number of pouches:
\[ \text{Pencils in each pouch} = \frac{\text{Total pencils}}{\text{Number of pouches}} = \frac{8}{2} = 4 \]
So, Murray has 4 pencils in each pouch.
The correct answer is 4.
