Question 118510: I need to take a real-life situation and create an equation or inequality that could be used for analysis, prediction, or decision making. Then, draw a graph to depict the variables in my siuation. Use the graph and what you know about linear inequalities to discuss the significants of your finding.
My real-life siuation is comparing cell phone plans. I have two plans
29.99 a month for 200 minutes and $.45 each additional minute. The other is 29.99 a month for 300 minutes and $.40 each additional minute. They each have an activation fee of 90.00. I am confused on how to write this in a equation or inequality and how to create the graph. I believe once I figure out the equation then the graph should come out correctly. Thank you for any help that you can give.
