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		$280,000		$300,000
2		280,000		300,000
3		280,000		300,000
4		280,000		300,000

The wind turbines require an investment of $887,600, while the biofuel equipment requires an investment of $911,100. No residual value is expected from either project.

Required:

1a. Compute the net present value for each project. Use a rate of 6% and the present value of an annuity of $1 in the table above. If required, round to the nearest dollar.

	Wind Turbines	Bio Fuel 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

Bio Fuel 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 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 percent.
