Problem above continued. By applying the EOQ model, we have EOQ$=500$ and the corresponding annual ordering cost is $45.$ Based on this information, which of the following statements is INCORRECT?

If we order $)$ each time, the annual holding cost is $45$

If we order $400($less than EOQ $)$ each time, the annual holding cost must be below $45.$

If we order $600($more than EOQ $)$ each time, the annual ordering cost must be above $45.$

If we order $600($more than EOQ $)$ each time, the total annual cost $($ordering $+$ holding$)$ must be above $90.$

All of the above statements are correct.
