THIS PROBLEMS HAS BEEN SOLVED.

Below are two word problems, I am pretty sure I did them correctly (if not please advise on what I am doing wrong), however, I need to graph them as well, and I am so lost. I have went through my text and did some Internet searches but I am not having much luck so if someone could explain how I would graph these, I would really appreciate it.

Thank you very much in advance for your time
