Assignment 6 3 Question 2: A company faces the following capital budgeting decision. Four real estate projects are available for investment. The net present value and expenditures required for each project (in millions of dollars) are as follows: Project 1 2 3 4 Net Present Value ($ Millions) 10 6 11 14 Expenditure Required ($ Millions) 70 35 80 60 The budget for this investment period is $200 million. If either project 1 or 4 is undertaken, they must both be undertaken. At most, one of projects 1 and 2 can be undertaken. Project 3 has to be undertaken if Project 4 is undertaken. Formulate an optimization model to find the projects to invest that maximize the total net present value while satisfying all project restrictions and not exceeding the budget. (Do NOT solve the model.) (20 points)
