Jamie can work no more than 20 hours a week this summer. She needs to earn at least $256 a week to save enough for a car before school starts. She makes $6 an hour babysitting and $16 an hour cleaning houses. Graph the system of inequalities that models the situation. Let x be equal to hours spent babysitting and y be equal to hours spent cleaning houses. Excluding the boundaries, place a point inside the region of the graph that satisfies the system.
