The Problem of Frames-R-Us
Step 1: Identify the Variables
Variables are those quantities whose values, once determined, constitute the solution to the problem. To identify the variables, ask yourself the following questions:
•What items can you choose and/or control?
•What decisions do you have to make?
•What factors affects costs and/or profits?
•If you were the person implementing the solution, what information would you need to know?
F1 = the number of frames of Type 1 to produce, F2 = the number of frames of Type 2 to produce, F3 = the number of frames of Type 3 to produce,
