The management of Advanced Alternative Power Inc. is considering two capital investment projects. The estimated net cash flows from each project are as follows: Wind Turbines Biofuel Equipment Year 1 $240,000 $430,000 2 240,000 430,000 3 430,000 240,000 240,000 4 430,000 The wind turbines require an investment of $685,200, while the biofuel equipment requires an investment of $1,305,910. No residual value is expected from either project.

Compute the net present value for each project. Use a rate of 10% and the present value of an annuity of $1 in the table above. If required, use the minus sign to indicate a negative net present value. If required, round to the nearest whole dollar. Wind Turbines Biofuel Equipment Present value of annual net cash flows 760,800 $ -1,331,400 X Less amount to be invested 685,200 1,305,910 Net present value 75,600 25,490 x 1b. Compute a present value index for each project. If required, round your answers to two decimal places. Present Value Index Wind Turbines 1.11 Biofuel Equipment 1.02 X 2. Determine the internal rate of return for each project by (a) computing a present value factor for an annuity of $1 and (b) using the present value of an annuity of $1 in the table above. If required, round your present value factor answers to three decimal places and internal rate of return to the nearest whole percent.
