I'm not sure if that's what you mean, but the difference between 6010 and 5060 is 950, so to find a number in a halfway between them I divided 950 by 2 (which is 475) and added it to 5060 (or substracted from 6010 - it's the same). Next I added the same number (475) to 6010. So finally it would like like this:
6,485 ; 6,010 ; 5,535 ; 5,060

Answer:
The store mixes 8 pounds of peanuts and 9 pounds of raisins.
Step-by-step explanation:
Let the store mixes 'x' pounds of peanuts and 'y' pounds of raisins.
The cost of peanut per pound is $3.20 and cost of raisins per pound $2.10
According to question,
Total weight of mixture given is 17 pounds.
................(1)
also total cost of mixture given is $44.50
...........(2)
Solving for equation (1) and (2),
Multiply equation (1) by 3.20 , we get
(1)⇒
............(3)
Now, subtract equation (3) from equation (2) , we get
![3.20x+2.10y-(3.20x+3.20y)=44.50-54.40](https://tex.z-dn.net/?f=3.20x%2B2.10y-%283.20x%2B3.20y%29%3D44.50-54.40)
![\Rightarrow 3.20x+2.10y-3.20x-3.20y=-9.90](https://tex.z-dn.net/?f=%5CRightarrow%203.20x%2B2.10y-3.20x-3.20y%3D-9.90)
![\Rightarrow 2.10y-3.20y=-9.90](https://tex.z-dn.net/?f=%5CRightarrow%202.10y-3.20y%3D-9.90)
![\Rightarrow -1.1y=-9.90](https://tex.z-dn.net/?f=%5CRightarrow%20-1.1y%3D-9.90)
![\Rightarrow y=9](https://tex.z-dn.net/?f=%5CRightarrow%20y%3D9)
Thus, The store mixes 9 pounds of raisins.
Put, y = 9 in (1),
![\Rightarrow x+y=17 \Rightarrow x+9=17 \Rightarrow x=8](https://tex.z-dn.net/?f=%5CRightarrow%20x%2By%3D17%20%5CRightarrow%20x%2B9%3D17%20%5CRightarrow%20x%3D8)
Thus, The store mixes 8 pounds of peanuts.
