What is the net present value of a project that has an initial cash outflow of $21,000 and the following cash inflows if the required return is 12 %? should we accept the project? Years Cash Inflows 1 $8,500 2 $7,120 3 $6,450 4 $4,900 Calculate the IRR of an investment that costs $77,500 and generates cash flow of $27,500 a year for four years? When should we accept the project? You discover the engine-oil additive your scientists developed three years ago makes a great men's after-shave once diluted properly using certain chemicals. If you want to assess today if you should go ahead with the production of this after-shave or not, would you consider the original $125,000 of R&D expenditures that went into developing the engine-oil additive as a relevant cash outflow in your assessment? Explain.
