How many pounds of nuts selling for $12 per lb and raisins selling for $6 per lb should a person combine to obtain 60lbs of trail mix selling for $8 per lb.
---------
Quantity:: t + s = 60 lbs
Value::: 12t+6s = 8*60 dollars
-------------------------------------
Modify for elimination:
t + s = 60
2t + s = 80
----------------
Subtract and solve for "t":
t = 20 lbs (amt of $12 nuts needed)
------
s = 60-t = 40 lbs (amt. of $6 nuts needed)
