Compute this machine's payback period, assuming that cash flows occur evenly throughout each year. Compute net present value for this machine using a discount rate of 8%. (Do not round intermediate calculations. Negative amounts should be entered with a minus sign. Round your present value factor to 4 decimals and final answers to the nearest whole dollar.) Table B.1* Present Value of 1 p=1/(1+i)n Table B.2' Future Value of 1 f=(1+i)n Table B.3 Present Value of an Annuity of 1 p=[11/(1+i)n]/i Table B. 4 Future Value of an Annuity of 1 f=[(1+i)n1]/i
