Tom Bergman, owner and operator of the Earplug Superstore, is reviewing the costs associated with the store’s best-selling hearing aid, the BZ15. The data available to Mr. Bergman concerning this device follow.
Demand = 25 units/week
Order cost = $3/order
Holding cos = $1.50/unit/year
The Earplug Superstore operates 52 weeks a year.
If Tom orders such that his annual holding cost is twice what his annual ordering cost is, how many units at a time is he ordering?
