The projected demand rate for an inventory item is $300$ units per week, and we use the item $52$ weeks per year We buy the item at a cost of $$30$ per unit. Our fixed ordering cost $("$S$")$ is $$100$ per order, and our annual carrying cost rate is $20\%.$ Our current ordering policy is to buy this item using an order quantity Q $=500$ units each time we reorder. Compute the long run average annual ordering cost $($AOC$)$ if we use the $($rounded$)$ EOQ order quantity computed above.
