Patricia Shrills is considering an expansion of one of its existing buildings to add more manufacturing space for its kid-friendly noisemakers, Several possible scenarios exist for future cash flows, as follows. 1. Construction costs of $501,000; steady sales and costs each year, netting to an annual operating cash inflow of $71,000; the expansion would have no salvage value at the end of its 10-year useful life (the building would be repurposed for a different product). 2. Construction costs of $501,000, rising and then falling net cash flows each year for 10 years, as follows: $50,000 for the first 2 and last 2 years, $176,000 for years 35, and $98,000 for years 68. 3. Construction costs of $704,000 : no cash flows in year 1,$74,000 in years 2 and 3,$150,000 in year 4,$101,500 in years 58, and $49,000 in the last 2 years. (a) Calculate the simple payback period for all three scenarios. (Round answers to 2 decimal places es. 15.25.)
