--------------
Equation:
dark + dark = dark
0.50x +0.80(100-x) = 0.68*100
--------
50x +80*100 - 80x = 68*100
-30x = -12*100
x = (2/5)100
x = 40 lb (amt. of 50% chips needed)
100-x = 60 lb (amt. of 80% chips needed)

n lb 50%; gives 50n
(100-n) lb 80% gives 80(100-n)
Total 100lb 68% 6800
6800=50n+8000-80n
30n = 1200
n=40
40 lb 50/50 and 60 lb 80/20
