Solutions

Expert Solution

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
