Please help me understand Part A. Correct anwers are shown in image. I am using EOQ = [(2 * demand * ordering cost) / holding cost per unit]:

EOQ = [(2 * 725 * $45) / $4]

EOQ (65300 / $4)

EOQ (16325)

EOQ 127.87, rounded to two decimal places = 128

128 = WRONG answer, can someone please explain why?
