7. Consider a zero-one model for the R&Dor capital budgeting problem. Assume that you have five projects like the ones in Problem #3 (on p 8-14). Now assume that there are the addi- tional constraints expressed below. Write the equalities (or inequalities) for these constraints: a. Any two of the first four projects must be undertaken b. Projects x, and x, must be taken simultaneously or not taken at all. c. Project *, will be undertaken only if xs is undertaken but xs is not conditional on X (ies, you can have x; without x,, but you cannot have x, unless X is undertaken). 7.
