There are three workers on campus. Each worker has 10 hours available, which then can spend on some combination of two activities: cleaning classrooms and fixing computers. Here are their production abilities (per hour): Worker 1: clean 1 classroom or fix 1 computer Worker 2: clean 1 classroom or fix 2 computers Worker 3: clean 2 classrooms of fix 1 computer How many total items (clean classrooms and fixed computers) could be produced if each worker spent half their time on each activity
