2	$150,000	$150,000
3	$250,000	$200,000
4	$80,000	$200,000
5	$80,000	$200,000
IRR	42.2%	39.3%

1. Calculate the projects net present value (NPV). Identify which project should be accepted under the rule of NPV. Explain your answer.

2. What is the decision based on the internal rate of return (IRR)?

3. Calculate the crossover rate/incremental IRR, at which the NPV profiles for Projects A and B intersect.

4. Which project should be accepted based on your answer in part (iii)? Explain your answer.
