The living expenses of college students should be 1200 to 1500. When the cost of living is 1200, you can spend one day in 40 yuan, and breakfast is 10 yuan, and lunch and dinner are 15 yuan respectively. Nowadays, most college students seldom eat breakfast. Many college students will lose weight, reduce the chances of having dinner and use the remaining money to buy what they want. So in general, when the living expenses are 1200 yuan, you can only eat, use the money saved to do other things, or do part-time jobs yourself, so that you can do your own expenses.

When you spend 1500 yuan, there is more money left. If you eat every meal every month, there will be 300 yuan left. You can have dinner with your classmates once or twice a month, which can enhance friendship. Therefore, when living expenses 1200 yuan, you can only solve your own food and clothing, and when 1500 yuan, you will have more choices.
