Let me make a rough calculation,
1. Bus ticket to school in the morning and evening 10 yuan;
2. Buy breakfast at 10 yuan.
There is 10 yuan left, which is not enough for me to buy my beloved pencil case. What should I do? I have to give my deskmate a birthday present. Alas, my mother is so stingy.
When I came home on Tuesday afternoon, I found books and pencils for dealing with new words in front of my house. New words cost 50 cents at school, but only 30 cents here. Pencil school buys 1 yuan, and here it sells 50 cents. I wholesale 20 new word books, * * * 6 yuan money, because pencils are not easy to sell, I wholesale 8.
After arriving at school on Wednesday, I sold wholesale notebooks and pens to my classmates one after another, each of which was cheaper than that sold by the school 1 dime.
It was finally sold out on Thursday, earning 5.2 yuan.
On Friday, I used the leftover 15 yuan to buy a pencil case and a present from my deskmate. I am very happy and flattered.
