Proposals A, B, C, D, E, F and G are being considered with money flows over 10 years. Proposal (A and E) are mutually exclusive, (C and D) are also mutually exclusive, and proposal B depends on C or D. The MARR is set at 10% and the amount of money available for investment is $110,000 ? When formulating the budget allocation problem with linear programming, the decision variables are xA,xB,xC,xD,xE,xF,xG. The investments for these proposals are IA,IB,IC,ID,IE,IF,IG. The net present values for these proposals are NPVA,NPVB,NPVC,NPVD,NPVE,NPVF,NPVG The constraint for the limited budget should be: xjIj110,000(j=A,B,,G) None of them Ij110,000(j=A,B,,G) xjIj110,000(j=A,B,,G) Ij110,000(j=A,B,,G) Proposals A, B, C, D, E, F and G are being considered with money flows over 10 years.
