Many students like to play sports and the equipment that goes with it costs money. The resource sets up an inequality that gives a total amount needed to purchase the equipment and the initial amount of money already obtained. In order to make more money, the subject decides to earn it by washing windows. It is up to your savvy consumers to write and solve an inequality that represents the number of windows washed. The final step is to graph the solution on a number line. Ask your class, what limits the number of windows they could wash if they wanted to save money?
