A factory has to transport raw materials to a project site. The total weight of the raw material will not be less than 1,500 tons. The factory manager plans to use two different trucking firms. Big Red has heavy-duty trucks that can transport 200 tons at a cost of $50 per truckload. Common Joe is a more economical firm, costing only $20 per load, but its trucks can transport only 90 tons. The factory manager does not wish to spend more than $450 on transportation. The availability of trucks is the same for both firms. What equation will show the manager's transportation spending limits? Replace the inequality sign with the equal sign. Use the Graph tool to graph the resulting equation and paste it into the box below. Describe which part of the graph should be shaded and whether the line should be dashed or not.
