DVD Rental Plans

Compare two DVD rental plans from a video store. You can change the monthly fee and per-DVD charge for each plan. The equations, graph, and table can be shown and adjust automatically as the values change. You can trace the value for a specific number of DVDs for each plan, and when appropriate, show the intersection point where the plans have the same total cost (show the solution to the system of two equations on the graph).
