Himig has two part-time jobs, as an assistant worker in a fast food chain (Job 1) and and as a receptionist at a small hotel (Job 2). Due to her heavy load in her studies, Himig can only render 12 hours a week in her jobs. She has determined that for every hour she works at Job 1, she needs 2 hours of preparation time, and for every hour she works at Job II, she needs one hour of preparation time, and she cannot spend more than 16 hours for preparation. If Himig makes Php 40 an hour at Job 1, and Php30 an hour at Job 2, how many hours should she work per week at each job to maximize her income? (Let x = Job 1; y = Job 2). What are the three constraints? * 6 points x 2 0 ; y 2 0 2x + y s 16 x + y s 12 2x + y > 16 x < 0; y s0 X + y 2 12
