Current decision to buy: Ross White's machine shop uses 200 brackets each month during the course of a year. This usage is relatively constant throughout the year. Currently, these brackets are purchased from a supplier 100 miles away for $16 each and the lead time is 2 days. The holding cost per bracket per year is $1.60 (10% of the unit cost) and the annual ordering cost per order is $18.50. There are 240 working days per year.
