The local theater in Jamie's home town has a maximum capacity of 160 people. Jamie shared with Venus the following graph and said that the shaded region represented all the possible combinations of adult and child tickets that could be sold for one show

You might want to show the graph. :]

To analyze the shaded region in the graph that represents all the possible combinations of adult and child tickets, it would be helpful to have access to the graph you mentioned. Please provide the graph so that I can help you understand it better and explain how to interpret it.
