Haroon letsX1=number of hrs sleep needed per weekx2= number of personal hrsx3= number of hours of studyx4= number of hours of sicial activityHe thinks that students should study 30 hours a week to have time to absorb material. This is his most important goal. Haroon feels that students need at most 7 hours sleep per night on average and that this goal is number 2. He believes that goal number 3 is to provide at least 20 hours per week of social time.(a) Formulate this as a goal programming problem.(b) Solve the problem using computer software.
