Domestic Robots R Us (DRRU), a subsidiary of AI Electronics Inc, are considering three new robots for their offering of AI driven domestic robots. Unfortunately, DRRU are subject to tight capital constraints, preventing them from putting all three robots into production should all three robots prove to create shareholder value. Indeed, the maximum investment DRRU can make this year is $55 million.

DRRUs cost of capital is 12% and the management are confident that each of the three robots or projects has the same risk as DRRUs existing projects.

1. While keeping in mind what you concluded in the previous step, assess all three projects by computing the following:
2. NPV,
3. IRR,
4. Payback period, and
5. Profitability index
