Consider the following linear program. Max3A+2Bs.t.1A+1B103A+1B271A+2B18A,B0 The value of the optimal solution is 28.5. Suppose that the right-hand side for constraint 1 is increased from 10 to 11 . (a) Use the graphical solution procedure to find the new optimal solution. What is the value of the objective function at the optimal solution? at(A,B)=() (b) Use the solution to part (a) to determine the dual value for constraint 1. (c) The computer solution for the linear program provides the following right-hand side range information. What does the right-hand side range information for constraint 1 tell you about the dual value for constraint 1 ? The range for constraint 1 is to . As long as the right-hand side stays this range, the dual value of is applicable. The value of the optimal solution will increase by for every unit increase in the right-hand side of constraint 2 as long as the right-hand side is the range to
