Buy stationery

Today, I bought 10 envelopes in Xinhua Bookstore. For each of the 3 corners, I bought a greeting card to send a letter. I also bought 2 pens, each 1.5 yuan, and bought a correction with 4.5 yuan. These things are used for my next semester. I bought 2 books and 1 is a foreign language book. A textbook for mathematics is 4.5 yuan per book. I also bought a book for 16.8 yuan. Today, I shared 36.3 yuan. I paid 100 yuan for the counter and recovered 64.3 yuan.

Today, I bought so many things! I am very happy!
