Net Present Value Method, Internal Rate of Return Method, and Analysis for a Service Company 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 Biofuel Year Turbines Equipment 1 $170,000 $360,000 2 170,000 360,000 3 170,000 360,000 4 170,000 360,000 The wind turbines require an investment of $516,290, while the biofuel equipment requires an investment of $1,027,800. No residual value is expected from either project, Present Value of an Annuity of $1 at Compound Interest Year 6% 10% 12% 15% 20% 1 0.943 0.909 0.893 0.870 0.833 2 1.833 1.736 1.690 1.626 1.528 2.673 2.487 2.402 2.283 2.106 4 3.465 3.170 3.037 2.855 2.589 5 4.212 3.791 3.605 3.353 2.991 6 4.917 4.355 4.111 3.785 3:326 2 5.582 4-868 4.564 4.160 3.605 6.210 5.335 4.965 4,487 3.837 9 6.802 5.759 5.328 4.772 4033 7.360 5.145 5.650 5.019 4.192 8 6.210 5.335 4.968 4.487 3.837 9 6.802 5.759 5.328 4.031 4.772 5.019 10 7.360 6.145 5.650 4.192 Required: la. 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, L a negative net present value. If required, round to the nearest whole dollar. Wind Turbines Biofuel Equipment Present value of annual net cash flows Less amount to be invested Net present value 1b. Compute a present value index for each project. If required, round your answers to two decimal places. Present Value Index Wind Turbines Biofuel Equipment 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 table above. If required, round your present value factor answers to three decimal places and internal rate of return to the nearest whole percent.
