Problem 10-8 Calculate the NPV at 10% and the IRR for the following projects. Round the answers to two decimal places. Use a minus sign to indicate a negative NPV. a. An initial outlay of $69,724 and an inflow of $15,000 followed by four consecutive inflows of $17,000. Do not round intermediate calculations. Round PVF and PVFA values in intermediate calculations to four decimal places. NPV IRR b. An initial outlay of 25,424 followed by two zero cash years and then four years of inflows at $10,500. Do not round intermediate calculations. Round PVF and PVFA values in intermediate calculations to four decimal places NPV IRR intermediate calculations to four decimal places. NPV IRR c. An outlay of10,672 followed by another outlay of $5,000 followed by five inflows of $5 000. Do not round intermediate calculations PVF and N A values n o n
