Consider the following linear program. Max3A+2Bs.t.1A+1B103A+1B221A+2B16A,B0 (a) Use the graphical solution procedure to find the optimal solution. What is the value of the objective function at the optimal solution? at(A,B)=() (b) Assume that the objective function coefficient for A changes from 3 to 5 . Use the graphicol solution procedure to find the new optimal solution. Does the optimal solution change? The extreme point ( optimal. The value of the objective function becomes (c) Assume that the objective function coefficient for A remains 3 , but the objective function coefficient for B changes from 2 to 4 . Use the graphical solution procedure to find the new optimal solution. Does the optimal solution change? The extreme point. ( optimal. The value of the objective function becomes (d) The computer solution for the linear program in part (a) provides the following objective coefficient range information. Use this objective coefficent range information to answer parts (b) and (c). The objective coefficient range for variable A is to since the char-ge in part (b) is solution change. The objective coefficient range for variabie B is range, we know the optimal solution change
