IRR, investment life, and cash inflows: Oak Enterprises accepts projects earning more than the firm's 13% cost of capital. Oak is currently considering a 10-year project that provides annual cash inflows of $15,000 and requires an initial investment of $101,100. (Note: All amounts are after taxes.)

a. Determine the IRR of this project. Is it acceptable?

b. Assuming that the cash inflows continue to be $15,000 per year, how many additional years would the flows have to continue to make the project acceptable (that is, to make it have an IRR of 13%)?

c. With the given life, an initial investment of $101,100,and cost of capital of 13%, what is the minimum annual cash inflow the investment would have to provide in order for this project to make sense for Oak's shareholders?
