The following questions refer to a capital budgeting problem with six projects represented by 0-1 variables x1, x2, x3, x4, X5, and x a. Write a constraint modeling a situation in which two of the projects 1, 3, 5, and 6 must be undertaken. b. Write a constraint modeling a situation in which, if projects 3 and 5 must be undertaken, they must be undertaken simultaneously. c. Write a constraint modeling a situation in which project 1 or 4 must be undertaken, but not both.
