1 CHAPTER 3 MP REVIEW PROBLEMS 1. Let x1 = barrels of beer produced x2 = barrels of ale produced Then we should solve max z = 5x1 + 2x2 s.t. 5x1 + 2x2 60 2x1 + x2 25 x1, x2 0 Graphically we find the optimal solution to be z = 60, x1 = 10, x2 = 5, x1

1 SOLUTIONS TO MP CHAPTER 5 PROBLEMS SECTION 5.1 1. Typical isoprofit line is 3x1+c2x2=z. This has slope 3/c2. If slope of isoprofit line is <2, then Point C is optimal. Thus if 3/c2<2 or c2<1.5 the current basis is no longer optimal. Also if th
