Enola must sell at least $570 worth of tacos and burritos each day. Also, she can sell at most 40 tacos and a minimum of 80 burritos. If xx represents the number of tacos sold and yy represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
