A student earns $13 per hour for tutoring and $5 per hour as a teacher's aide. Let x = the number of hours each week spent tutoring and y = the number of hours each week spent as a teacher's aide. Complete parts (a) through (e). www. a. Write the objective function that describes total weekly earnings. Z= (Do not include the $ symbol in your answer.) b. The student is bound by three constraints Write an inequality for each constraint 1. To have enough time for studies, the student can work no more than 17 hours per week 2. The tutoring center requires that each tutor spend at least three hours per week tutoring ZA 3 The tutoring center requires that each tutor spend no more than eight hours per week tutoring c. Graph the system of inequalities in part (b) Use only the first quadrant and its boundary because x and y are nonnegative Use the graphing tool to graph the system
