Answer: $3.25

Step-by-step explanation:

First you need to calculate the cost of the 8 pounds of nuts.

Cashews = 4 x $4 = $16

Peanuts = 4 x $2.50 = $10

The total cost of 8 pounds of nuts equals $16 + $10 = $26

In order to calculate the cost of 1 pound of the mixture you need to divide the total cost by the total weight.

$26 / 8 lbs = $3.25 / lb

The cost of one pound of the mixture is $3.25.
