IRR, investment life, and cash inflows Oak Enterprises accepts projects earning more than the firm's $12\%$ cost of

capital. Oak is currently considering a $12-$year project that provides annual cash inflows of $$50,000$ and requires an

initial investment of $$378,100.$

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

b$.$ Assuming that the cash inflows continue to be $$50,000$ 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 $12\%)?$

c$.$ With the given life, an initial investment of $$378,100,$ and cost of capital of $12\%,$ 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?
