inventory control manager for Cal-Tex, receives wheel bearing from Wheel
Rite, a small producer of metal parts. Wheel Rite can produce only
500 wheel bearings per day. Cal Tex receives 10000 wheel bearings
fro Wheel Rite each year. Because Cal Tex operates 200 working days
each year, its average daily demand of wheel bearings is 50. Ordering
costs for Cal Tex is $40 per order, and carrying costs is $0.60 per wheel
bearing per year. Wheel Rite has agreed to ship the maximum number
of wheel bearings that it produces each day to Cal-Tex once an order has
been received. How many wheel bearings should Cal Tex order at one
time?
