School starts in September, 2065 438+03- 10, and holidays in October, 20 14. Theoretically, our school time is five months, about 150 days, with an average of 2 1 week and 1 day for 24 hours. * * * The school time is 3,600 hours, excluding the National Day holiday and 15 * * 12 days of final examination time-at least 7 days of Saturday and Sunday rest time ***42 days, so our real study time at school is 150 days-12-7-.

Calculate our time by the hour.

Our real study time at school is 24: 00 every day for 89 days, 24: 00 X89 days =2 136 hours, except that the non-study time is 3 hours every day from 6: 00 to 9: 00 in the evening, so 89 days X3 time =267 hours, except that the sleeping time is 22: 00 to 7: 00 in the morning. So 89 days X9 =80 1 hour, so our real study time is 7: 00-6: 00, 2136-801:267 = 1068, which is exactly the study time = rest time+play time/.

Our real study time is 1068 hours, ***44.5 days. And there is no time for lunch break, breakfast and lunch.

From the point of view of money

We 13 large class, ***26 small classes, 26x2 1 week =546 classes, excluding holidays, 12 days, the final exam is 7 days, *** 19 days, about 3 weeks. 3 weeks X26 =78, excluding the first nine weeks of foreign trade, 18, so our real class time is 546 -78-18 =450 hours, and our tuition fee is 1 1000 yuan /450 classes = 24 yuan per class, that is. Average daily 24 yuan, X6 classes =

Students, our real class time is 44.5 days, and we have to pay the tuition fee of 144 yuan every day. Seeing this, everyone should think about themselves. What reason do we have to skip class and ask for leave?
