c$)$ Caravan Engineering uses the following formulas to determine the annual ordering costs and annual holding costs for its temperature probe casings:

Annual Ordering Costs $=$ D$/$Qo S$,$ and Annual Holding Costs $=$ Qo$/2$ H

where Qo $=60$ units is the order quantity, D is the annual demand, S is the ordering cost, and H is the annual holding cost per unit. The firm$$s annual demand is two hundred units, the ordering cost is eighteen dollars, and the annual holding cost is two dollars per unit. The firm$$s inventory manager wants to calculate the annual ordering costs, and the annual holding costs.
