Madelyn owns a food truck that sells tacos and burritos. She only has enough supplies to make 120 tacos or burritos. She sells each taco for $3.25 and each burrito for $7.50. Madelyn must sell at least $600 worth of tacos and burritos each day. If x x represents the number of tacos sold and y y represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
