Compo- nents purchased from Supplier B are priced at 5 each and are used at the rate of 4,500 units per month. Components purchased from Supplier Care priced at 9 each and used at the rate of 1000 units per month. Currently, O'Donnell & Joyce purchases a separate truckload from each supplier.

The trucking com- pany charges a fixed cost of 550 for the truck with an additional charge of 120 for each stop.
