Given the following two tables with financial and subjective scores on three projects, create MS Excel models to compute each of the following selection criteria for each project: 1) NPV (discounting factor is 8%) 2) IRR 3) ROI (at least 10% required) 4) Payback period (maximum 2 years) 5) Weighted score (using weighted scoring model)

Can i know the right steps of each please?
