Antique manufactures old$-$fashioned telephones for use in movie scenes $($and other displays$).$ Antique's annual demand for rotary telephones is $33,000$ units per year, so it needs just as many receptors to assemble the phones. Receptors are ordered from a supplier, and shipping and handling costs are $$15$ per order $($regardless of how many units are on order$).$ The holding costs are $$4/$unit$/$year$.$ If the current company policy calls for orders of $3,000$ receptors, what are the total annual inventory costs for the receptors?
