PLEASE PLEASE HELP ME 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.

Part A
What inequality will show the number of trucks used to transport the required raw material? Replace the inequality sign with the equal sign. Go to your math tools and open 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.
Part B
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.
Part C
If the manager wants to use more Big Red trucks than Common Joe’s trucks, plot a graph that shows the number of trucks used, given all 3 constraints. Replace the inequality sign with the equal sign. Use the Graph tool to graph all three equations and paste the resulting graph into the box below. Describe which part of the graph should be shaded and whether the lines should be dashed or not.
