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

The wind turbines require an investment of $$913,600,$ while the biofuel equipment requires an investment of $$1,579,290.$ No residual value is expected from either project.

Required:

$1$a$.$ 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.

$1$b$.$ 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.
