(LP for previous question (2)):

(5 pts) Refer to Problem 2 and suppose the budget is increased to $600,000 and that the additional engineers or additional staff (but not both) can be hired so that only one of the engineer or staff limitations must hold (i.e. at least one of the two constraints holds). Also, if project 2 is performed, project I will not be performed, at least two of projects 1, 2, and 3 should be performed, and if project 3 is performed, project 4 should be performed. Which projects should Western undertake under these conditions? Provide LP formulation only. Decision Variable: Let, Xi = 1 if project iis selected otherwise Xi = 0 Where, i = 1, 2, 3, 4, 5, 6 for the six projects Objective Function: Objective is to maximize net present value by selecting the projects: Max Z = 100*X1 + 145*X2 + 200*X3 + 250*X4 + 500*X5 + 695*X6 Part a: Subject to: Cost requirement and budget availability constraint: (total cost required for project
