Note that after having the rounded-up EOQ, you should not round up values at intermediate steps; and, you should round T up only after the last calculation. (For example: enter 10 for 10 days.) (b) What is the current inventory position (IP) in bottles? (For example: enter 70 for 70 bottles) (c)Without safety stock, what is the replenishment level without safety stock M(AD) in bottles? Note that the question does not ask for M(ST). (For example: enter 70 for 70 bottles)
