Homework Help: Linear Programming

  1. Feb 17, 2009 #1
    For the first part (i) i found the optimal solution when x1=180,x2=40 and the optimal is 258.
    in (II) for the protein we have these 2 functions :PAx1+1.10x2 and 4x1+2x2=700
    i found 2.2 and for cyrbohydrate with the functions :PAx1+1.10x2 and 3x1+x2=300
    i found 3.3 so the first is 2.2<=PA<=3.3
    For PB for the protein we have these 2 functions :1.50x1+PBx2 and 4x1+2x2=700
    i found 0.75 and for cyrbohydrate with the functions: 1.50x1+PBx2 and 3x1+x2=300
    i found 50. so the second is: 0.75<=PB<=50. AM I right?

    For the (III) part for protein i have:4x1+2x2=701 and 3x1+x2=300
    and i found that the shadow price is: £162.9
    For the cyrbohydrate i have:4x1+2x2=700 and 3x1+x2=301 and i found
    that the shadow price is:£161.3

    Can someone please check my answers and help me for the last part please??????? I don't know how to write a memo. If someone please can do the first steps????
    Thank you very much MARIA.
