Score: 0 of 1 pt 4 of 16 (12 complete) HW Score: 59.38%, 9.5 of 16 pts X Instructor-created question Question Help You are reviewing the anlaysis of an investment project done by one of your staff. You find the analysis is correct except for having ignored changes in net working capital. You expect the project to require an increase in net working capital of $82000 at the start, an increase of $28700 more after year 1, a decrease of $41000 after year 4, and finally return all of the remaining net working capital after year 8, which is the end of the project. If the analysis had calculated an NPV of $68081, what is the project's revised NPV, including the effect of changes in net working capital, if the project's cost of capital is 9.7%?
