I need help with these problems for a quick vote, thank you

Leilani Lavender's law office has traditionally ordered ink refills 60 units at a time. The firm estimates that carrying cost is 40% of the $10.00 unit cost and that annual demand is about 240 units per year. The assumptions of the basic EOQ model are thought to apply. a) For what value of ordering cost would its action be optimal? Its action would be optimal given an ordering cost of $ per order (round your response to two decimal places). If D=8,500 per month, S=$47 per order, and H=$1.50 per unit per month, a) What is the economic order quantity? The EOQ is units (round your response to the nearest whole number). Lindsay Electronics, a small manufacturer of electronic research equipment, has approximately 7,000 items in its inventory and has hired Joan Blasco-Paul to manage its inventory. Joan has determined that 10% of the items in inventory are A items, 35\% are B items, and 55% are C items. She would like to set up a system in which all A items are counted monthly (every 20 working days), all B items are counted quarterly (every 60 working days), and all C items are counted semiannually (every 120 working days). How many items need to be counted each day? The total number of items that need to be counted each day is items (round your response to the nearest whole number)
