a. Determine the order quantity and reorder point.
Note: Use Excels NORMSINV( ) function to find your z-value and then round that z-value to 2 decimal places. Do not round any other intermediate calculations. Round your final answers to the nearest whole number.
Optimal order quantity =
Reorder point =
b. Determine the annual holding and order costs.
Note: Do not round any intermediate calculations. Round your final answers to 2 decimal places.
Holding cost =
Ordering cost =
c. Assume a price break of $50 per order was offered for purchase quantities of 2,200 units per order. If you took advantage of this price break, how much would you save annually?
