Leches operates a chain of sandwich shops. The company is considering two possible expansion plans. Plan A would open eight smaller shops at a cost of $8,400,000. Expected annual net cash inflows are $1,500,000, with zero residual value at the end of 10 years. Under Plan B, Leches would open three larger shops at a cost of $8, 250,000. This plan is expected to generate net cash inflows of $1,080,000 per year for 10 years, the estimated useful life of the properties. Estimated residual value for Plan B is $1,000,000.
