An investor is considering a business opportunity with the anticipated receipts and disbursements shown in the following table. Calculate the net cash flow representing this investment, and then find the present worth of the net cash flow for an interest rate of 0% and 12%. Answer: $175,000; -$12,915 An asset with an expected life of 4 years is to be purchased for $5,000. It is estimated that it will produce annual revenues of $2,000 while incurring annual expenses of $400. At retirement at the end of the fourth year it is estimated that the asset will be sold for $900. At that time it is expected that $700 will have to be paid to remove the asset from the plant. The interest rate is 8% compounded annually. Find the present worth of the receipts and the present worth of the disbursements and subtract the equivalent disbursements from the equivalent receipts. Find the net cash flow for this investment and calculate the net present worth from this cash flow. Compare your result with that of part (a). Given the cash flow shown, find the PW(i) as a function of i and graph the results
