6-35 Lisa Surowsky was asked to help in determining the best ordering policy for a new product. Currently, the demand for the new product has been projected to be about 1.000 units annually. To get a handle on the carrying and ordering costs, Lisa prepared a series of average inventory costs. Lisa thought that these costs would be appropriate for the new prod- uct. The results are summarized in the following ta- ble. These data were compiled for 10,000 inventory items that were carried or held during the year and were ordered 100 times during the past year.
