Kaylee 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 and each burrito for $6.
Kaylee must sell at least $480 worth of tacos and burritos each day. If x represents
the number of tacos sold and y represents the number of burritos sold, write and
solve a system of inequalities graphically and determine one possible solution.
