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.

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 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.
