Aimee works at a food kitchen, packaging dinners for families. Each dinner contains either 4 servings or 6 servings. Some dinners are reserved ahead of time, and others are available on a first come/first serve basis. There are 192 servings available today. There are reservations for eight 6-serving dinners and twelve 4-serving dinners. Write and graph the inequalities to show the possible combinations of 4- and 6-serving dinners that can be packaged.
