Verify your answer for the optimal order quantity obtained in$$part $($d$)$ by applying the EOQ formula by hand.$($f$)$ With the optimal order quantity obtained above, how Tim Madsen is the purchasing agent for Computer Center,$$a large discount computer store. He has recently added the hottest$$new computer, the Power model, to the store$$s stock of goods. Sales$$of this model now are running at about $13$ per week. Tim purchases$$these computers directly from the manufacturer at a unit cost of$$$$3,000,$ where each shipment takes half a week to arrive.$$Tim routinely uses the basic EOQ model to determine the$$store$$s inventory policy for each of its more important products. For$$this purpose, he estimates that the annual cost of holding items in$$inventory is $20$ percent of their purchase cost. He also estimates that$$the administrative cost associated with placing each order is $$75.$

inventory level be when each order is$$placed$?($g$)$ How much does the optimal inventory policy reduce the$$total variable inventory cost per year $($holding costs plus$$administrative costs for placing orders$)$ for Power model$$computers from that for the policy described in part $($a$)?$What is the percentage reduction
