2. Punkey Electronics, a small manufacturer of electronic research equipment, has approximately 7,000 items in its inventory. They just hired Joe Detail to manage the inventory. Joe has determined that 10% of the items in inventory are A items, 35% are B items and 55% are C items. He would like to set up a system where all the A items are counted monthly (every month has 20 working days), B items are counted quarterly (every 60 working days), and all C items are counted semiannually (every 120 working days). How many items of each classification and in total need to be counted each day?
