Lindsay Electronics, a small manufacturer of electronic research equipment, has approximately 7,200 items in its inventory and has hired Joan Blasco-Paul to manage its inventory. Joan has determined that 12% of the items in inventory are A items, 37% are B items, and 51% are Citems. She would like to set up a system in which all A items are counted monthly (every 19 working days), all B items are counted quarterly (every 62 workingi days), and all C items are counted semiannually (every 121 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).
Total number of items in inventory = 7200
Percentage of items in inventory that are A items = 12%
Number of A items in inventory = 7200 * 0.12
= 864
Number of days in which items A are counted = 19 days
Average number of items A that are counted each day = 864 / 19
= 45.47
Percentage of items in inventory that are B items = 37%
Number of B items in inventory = 7200 * 0.37
= 2664
Number of days in which items B are counted = 62 days
Number of items B that are counted each day = 2664 / 62
= 42.97
Percentage of items in inventory that are C items = 51%
Number of C items in inventory = 7200 * 0.51
= 3672
Number of days in which items C are counted = 121 days
Number of items C that are counted each day = 3672 / 121
= 30.35
The total number of items that need to be counted each day = 45.47 + 42.97 + 30.35
= 118.79, i.e. 119 items
