A large store is deciding whether to install a machine in each of its store. Each machine costs $250,000. Projected income per machine is as follows: Year 1 2 3 4 5 Sales 200,000 300,000 300,000 250,000 250,000 Operating Expenses 200,000 200,000 200,000 200,000 200,000 Depreciation 50,000 50,000 50,000 50,000 50,000 Accounting Income 0 50,000 50,000 0 0 Why would the store continue to operate a machine in Years 4 and 5 if it produces no profits? What are the cash flows from investing in a machine? Assume each machine is completely depreciated and has no salvage value at the end of its 5 years life. Show all your workings and justify your answer.
