Determine which projects should be implemented if the budget is at most $510,000 and the objective is to select the subset of projects that maximizes total NPV? Use the empty columns for your work, labeling whatever columns you use. Project Project Cost $200.000 $100,000 NPV $180.300 $310,100 $51.600 $26.800 $34.300 $122.400 $250.000 100,000 in is the stone frame
