Question 729079
 How many pounds of salted nuts selling at $1.60 per pound should be mixed with 2 pounds of salted nuts selling for $2.20 per pound to obtain a mixture selling for $1.72 per pound? 
----
Equation:
value + value = value
1.6x + 2.2*2 = 1.72(x+2)
-----
160x + 220*2 = 172x + 172*2
-------------------
12x = 48*2
x = 8 lbs. (amt. of $1.60 per pound nuts needed)
