During the Spring Festival, I always get lucky money from 600 yuan. I'm going to spend half and save the rest. 300 yuan, I plan to spend 40% on snacks and 60% on school supplies and books for the new semester. So, I went to Xinhua Bookstore first, chose the book 10, and spent 153.6 yuan. Then I went to the stationery store and bought a pencil case of 1, 16 yuan, 10 6 yuan money. School supplies cost 175.6 yuan.

Then I went to the supermarket and bought two bottles of drinks 10 yuan, three pieces of bread 15 yuan, 53.6 yuan of chocolate and 35 yuan1kloc-0/3.6 yuan.
