**Steve**, Wednesday, February 15, 2012 at 1:56pmlet c = cost of final solution

use x,y,z liters of the three solutions

x <= 1.0

y <= .5

z <= .4

x + y + z = .25

.05x + .28y + .40z = .17*.25

c = 28x + 38y + 50z

A little manipulation of tableaux (a google on linear programming will turn up zweigmedia) will show that

Optimal Solution: c = 8.89; x = 0.164, y = 0, z = 0.086

Hmmm. no 28% solution used.

optimal solution: c=191/23; x=2750/23; y=3000/23; z=0
