Identify a situation in your life/work previously or currently when you had a maximization or minimization decision to make that involved two decision variables and at least two binding constraints. This one could be tricky to apply to your personal/work life. If you're stuck you can do something like this: maximize income per week where the two decision variables are two different jobs (x1 and x2) with two different wage rates (coefficients to x1 and x2) and the constraints are the hours you are available to work (should include both decision variables) and the hours offered by the employer (should have one constraint per job).
