Mark Angelo sells $3,600$ electric motors each year. The cost of these runs $$200$ each, and demand stays constant throughout the year. The cost of placing an order equals $$40,$ while the holding cost $$20$ per unit per year. $360$ working days per year and the lead$-$time equals $5$ days. If Mark orders $200$ units each time he places an order, what would his total ordering cost sum for the year?
