ABC Corp is analyzing its current inventory policy on dog food. They order 700 bags every time they place an order. For this constant order size, they incur an annual holding cost of $480 and an annual ordering (set-up) cost is $1200. What do these calculations indicate about their dog food inventory policy? That they should switch to a periodic review inventory policy That ordering 700 bags is the optimal quantity to order That ordering 700 bags requires that they order too often and the quantity ordered should be increased That ordering 700 bags requires them to hold too much dog food and the quantity ordered should be decreased
