A grocer mixes peanuts that cost $1.49 per pound and walnuts that cost $2.69 per pound to make 100 pounds of a mixer that cost $2.21 per pound. How much of each kind of nut did the grocer put into the mixture?
-------
Weight Eq:: p + w = 100 lbs
Value Eq:: 149p + 269w = 221*100
------
Modify for elimination:
149p + 149w = 14900
149p + 269w = 22100
-----
Subtract and solve for "w"::
120w = 7200
---
w = 60 lb (amt. of walnuts needed)
100-w = 40 lb (amt. of peanuts needed)
