Goal 6: Solve word problems using the following process:
1) Define useful variables for a word problem
2) Write equations that correctly model the problem. (The problem might require only one equation, or it might require a system of equations.)
3) Answer the question in the word problem after solving the equation or system of equations you wrote to model the problem. (2 – 5, 7 – 4, and handouts)
