The management of Advanced Alternative Power Inc. is considering two capital investment projects. The estimated net cash flows from each project are as follows:

Year	Wind Turbines	Biofuel Equipment
1	$360,000	$680,000
2	360,000	680,000
3	360,000	680,000
4	360,000	680,000

The wind turbines require an investment of $1,093,320, while the biofuel equipment requires an investment of $1,941,400. 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
3	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
7	5.582	4.868	4.564	4.160	3.605
8	6.210	5.335	4.968	4.487	3.837
9	6.802	5.759	5.328	4.772	4.031
10	7.360	6.145	5.650	5.019	4.192

1a. 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. 1b. Compute a present value index for each project. If required, round your answers to two decimal places. 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. 3. The net present value, present value index, and internal rate of return all indicate that the is/are a better financial opportunity compared to the , although both investments meet the minimum return criterion of 10%
