Project Delta requires a $30,000 cash outlay today and is expected to generate after-tax cash flows of $7,000 in year 1, $9,000 in year 2, $11,000 in year 3, and $16,000 in year 4. Neither project can be repeated at the end of its life.

The appropriate discount rate for both projects is 10 percent.

b) Do NPV and IRR decision making tools agree with each other in terms of which project BC Bamboo should choose?

c) If they don't agree, which project should BC Bamboo choose? Explain your choice.
