Consider raw material #A with the following data:

Annual demand $=6,000$ units, Holding cost per unit per year $=$ $$720,$ Order cost $=$ $$80\mathrm{.}40$ per order, Raw material A is critical to production and perishable.

Calculate $($a$)$ EOQ, $($b$)$ TC$,($c$)$ # of orders$/$year$,($d$)$ order frequency, $($e$)$ Which model do you recommend?
