An investor is considering two investment propositions: OPTION 1: A small restaurant business can be purchased for $400,000 today. It is expected to produce net cash inflows from operations of $150,000 a year (at the end of each year) for 3 years, starting next year. At the end of the 3 years the business will be sold for $250,000. OPTION 2: A bigger restaurant can be purchased for $800,000. It is expected to produce net cash inflows of $210,000 at the end of each year for 4 years and would be sold for $500,000 at the end of that time. If the prospective investor has an opportunity cost of 15%, use NPV and IRR methods to help the investor decide whether they should purchase either of these restaurants. and if so, which one would be the best investment?
