1.	To Understand the problem (what are the information provided)
•	Read the problem and seek to understand what you need to find.
•	Sketch a diagram (if applicable) to visualize the problem.
2.	Devise a plan (use the information to form a relationship so as to form a quadratic equation)
•	Select a variable, for example, $x$ and define what it represents.
•	Formulate an inequality using an algebraic expressions formed in terms of the variable.
3.	Implement the plan (solve the inequality and illustrate the solution(s) on a number line if necessary)
4.	Check your answers (choose the appropriate value to solve the problem)
•	Interpret the solution in the context of the world problem.
