a. Write a system of inequalities that shows the possible number of students and adults that can attend in order to make at least $ 2100 with the limit of 600 people. b. Sketch (AND LABEL!) a graph of the inequalities in the coordinate plane on real graph paper. c. List three solutions from your graph and show that these solutions work. Give your answers in real life, not as an ordered pair. d. Is the point (500, 100) a solution to the system?​
