Abstract The article discusses possible valid combinations of replacement market-ceiling-floor-cost and demonstrate a computer solution that identified the lower of cost or market for accounting students. Allan R. Dreblin discussed twelve possible valid combinations. Meanwhile, Maurice A. Hartman presented a method to help the student find the lower of cost or market. Another method is applicable to all of the twelve combinations of replacement market-ceiling-floor-cost and does not involve exceptions
