Minmize z= 150x1 + 150x2 + 150x3 + 3i1 + 3i2 + 3i3 Subject to : x1 =< 3000, x2 =< 3000, x3 =< 3000 i1 = 30 + x1 - 2800 i2 = i1 + x2 - 2300 i3 = i2 + x3 -3350 Where it >= 0 and xt >= 0 (t = 1, 2, 3) Really need help *sighs* Any help would be seriously appreciated I think I have to find the optimal solution, the x1, x2, x3, i1, i2, i3 (to its minimum) Thanks again
