Rules for Solving **Optimization Problems** 1. Draw a diagram to represent the situation (if possible) 2. Determine the name and quantity which is to be minimized or maximized - assign letters to variables which may vary - express the quantity as a function of the variables 3. If more then 1 variable, find constraints to link variables 4. Simplify- always use constraint to express quantity as a function with a single variable 5. Find domain of 6. Find first and second derivative to find the solution
