1. Calculate the net present value (NPV) and annual equivalent value (AE) of the following cash flow diagram. The Minimum Acceptable Rate of Return (MARR) is 15%.
2. Calculate the IRR for the cash flow diagram.
3. Determine whether an investment made according to this cash flow is more profitable than doing nothing and just collecting the MARR. Explain your answer.(I don't need the ERR)
