O=1080x+6y-6zx O=number of times opened/closed X=number of years you've gone to school Y=number of school days attended this year Z=the average number of school days missed each year Assuming that you open and close your backpack twice in the morning, once when you get to school, once when you leave school, and twice during the evening.
