Examples of how to read this table: the IRR of project A is 9.6%, and the IRR of the incremental investment project when project A is compared to project B is 28.9%. 

1) If the alternatives are independent and the MARR is 18%, which alternative(s)should be selected? Explain your answer. 

2) If the alternatives are mutually exclusive and the MARR is 15% per year, which alternative should be selected? Explain your answer. For each comparison, also show the corresponding figure where you can compare the alternatives (.e., a figure with both alteratives at the same time).
