Use a system of inequalities to represent the situations described in Exercises 61 – 68, then solve the system using the methods developed in this section. In drawing the graph of your solution set, you may want to take into consideration that certain quantities cannot be negative and therefore you may want to restrict the solution set appropriately as we did in Example 9.
