 Procedure for Solving Applied Problems

Step 1  Read the problem as many times as needed to understand it thoroughly. Pay close attention to the questions asked to help identify the quantity the variable should represent.

Step 2  Assign a variable to represent the quantity you are looking for, and, when necessary, express all other unknown quantities in terms of this variable. Frequently, it is helpful to draw a diagram to illustrate the problem or to set up a table to organize the information.
