Estimate each projects payback period. Net Present Value (NPV), internal Rate of Return ORIO, Profitability index P), and Modified internal rate of return (MIRR) (50 points) 2. Which projector projects should be accepted if they are independent Why? (10 points) 3. Which project should be accepted if they are mutually exclusive? Why (10 points) 4. Estimate the crossover rate of these two projects. If the cost of capital is 10 and assuming X & Yare mutually exclusive, which project should be taken (20 points)
