Section 3.6 Writing Equations for Story Problems

Add this list of numbers. (without a calculator, paper, or pencil.)

Setting Up and Solving Story Problems Use the Problem Solving Method.

Problem Solving Method Ask- Read the problem carefully to determine what you are trying to find. Brainstorm- What can we use a variable to represent? Choose- Find the best way to define the variables. Demonstrate- Set up the equation and solve the problem. Evaluate- Does your solution answer the problem? (and seem reasonable)
