Today in class we did a warm up problem involving two earning situations, translated them into linear form, graphed each line, then found their intersection. We discussed what what the intersection of the two lines means and the significance of the slope.

We continued to work on the "Cell Phone Problem." The due date has been extended to Monday 12/16. Students were told to exchange info so they can complete their group assignment by the start of class on Monday. Be sure to review the rubric so you maximize the number of points you can earn on this assignment.
