Linear programming and capital rationing If we know the cash flow and NPV value for projects A, B, C, and D as presented in Table A. The projects are subject to several constraints. For one, the total cash outflow in period 0 cannot be more than the $18 million ceiling. In addition, we also know in the first period cannot be more than the $25 million ceiling. 1. Please use this information to set up objective function and constraints to be solved by Excel program. 2. Please describe the procedure of using Excel program to solve X4,XBXC, and XD. 3. When we get the optimal solution, what is the coefficient of the objective function should be?
