Question

Lindsay Electronics, a small manufacturer of electronic research equipment, has approximately 7,400 items in its inventory and has hired Joan Blasco-Paul to manage its inventory. Joan has determined that 11% of the items in inventory are A items, 32% are B items, and 57% are C items. 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 59 working 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)

Explanation / Answer

Total number of items to be counted are
= A Items to be counted + B items to be counted + C items to be counted
= (Total items * % of A items)/Number of working days when A is counted + (Total items * % of B items)/Number of working days when B is counted + (Total items * % of C items)/Number of working days when C is counted

= ((7400*0.11)/19) + ((7400*.32)/59) + ((7400*0.57)/121)
= 118 (rounded to the nearest whole number)
