Assume that you are presented with an investment opportunity that would cost $3,800 in today's money. Further assume that you can reasonably expect to generate $1,000 in income per year for each five years and that the prevailing cost of money or interest is 8%. The discount factors are (year 1: .926; year 2: .857; year 3: .794; year 4: .735; and year 5: .681). What would be the net present value(NPV), and should you except the opportunity?

Can you show step by step calculation?
