A company is considering two projects, Project X or Project Y, to expand production capacity for a popular consumer product. Project X involves acquiring a similar existing machine for $135,000, while Project Y is a more expensive $240,000 machine with greater capacity. The Chief Accountant calculated the net present value, profitability index, and discounted payback period for each project but remains uncertain which to recommend. The assistant is asked to perform the same calculations and discuss their relevance to the decision.
