In the simple EOQ model, demand is assumed to be constant. Thus, as order size increases, annual ordering costs $(1)....$ but annual inventory holding costs $(2).....$

$(1)$ remain the same $q,(2)$ increase.

$(1)$ decrease $q,(2)$ decrease

$(1)$ increase $q,(2)$ decrease.

$(1)$ increase $q,(2)$ increase.

$(1)$ decrease $q,(2)$ increase.
