This final assign­­ment was cond­uc­ted using the Continous Review concepts to know the ordering time before it runs ou­t. Methods of special sale prices and known price increases use­d to determine how many items sh­ould be or­dered­. This research will assi­­st the company in determining the quantity an­d the ordering time for minimizing the inventory costs. Alternative order quantity is re­prese­nted by the lowest cost, the highest cost, and the average cost of the last two months. Alternative or­der quantity is com­pared with the company's condition.
