As the owner of your small company, you must decide on taking or not taking on a new project. The project requires an RM90,000 investment and is expected to provide benefits of RM7,000 during years one through three, RM9,000 during years four through six, and a benefit of RM90,000 in year seven. The salvage value in year seven is going to be RM50,000.

Determine the NPW and IRR if the MARR = 15%. What would be your decision on the project? Please show the calculation from starting to end.
