How much average inventory should be carried if management wants the inventoryto be 4?

To determine the average inventory needed when management wants it to be at a specific level, such as 4, you would typically use the economic order quantity (EOQ) model or similar inventory management techniques. If "4" refers to units, then the average inventory should be maintained at that level to meet demand without overstocking. The actual inventory levels may vary based on lead times, sales forecasts, and safety stock requirements. Thus, management should continuously monitor and adjust inventory levels to align with changing demand and supply conditions.
