When my mother was cooking in the kitchen, she found that the soy sauce was gone, so she asked me to buy a bottle in the supermarket downstairs and gave me six empty bottles and two yuan.

When I got to the store, I first asked how much these six empty bottles could be exchanged. Aunt took a look and said that there are still two empty bottles that can't be changed. Is an empty bottle 1 cent? I calculated that 6-2=4 can be changed into 40 cents. Then I went to look for soy sauce and saw that there were several varieties of soy sauce, and the most expensive one was 8.50 yuan. If I buy an expensive one, I have 2 yuan plus the exchanged 0.4 yuan (8.50-2.40=6. 10). No, I didn't have enough money, so I chose a cheap bottle of 2.50, and I calculated (2.50-2.40). Aunt seemed to read my mind and came over and said? Little sister, take the soy sauce first and give me the missing 1 next time, will you? I quickly said thank you, aunt.

It turns out that there is mathematics everywhere in life. I will bring enough money when I go shopping next time.

This morning, my mother took me to the supermarket of Falian for shopping. When I arrived at the store, I didn't know what to buy because of the dazzling array of goods.

First, we came to the gourmet area. I chose Shanghaojia natural potato chips and Mengniu dried milk tablets, and my mother chose a bottle of vitamin chewable tablets for growth and happiness. Then we went to the electrical area and bought a Runxin repeater. Finally, we went to the daily necessities section and bought a San Xiao toothbrush.

It was then that my mother remembered that she had only one hundred dollars with her, and I didn't know if it was enough. I looked at all the commodity prices: Shanghaojia natural potato chips 4.8 yuan, Mengniu fresh milk dried tablets 13 yuan, San Xiao toothbrush 3.5 yuan, growth-happy vitamin chewable tablets 29.9 yuan, Runxin repeater 62 yuan. Then I estimated that it would be 1 13 yuan. I quickly told my mother that there was not enough money. We'll put the Happy Growth Vitamin Chewable Tablets back. Fortunately, I learned to calculate this time, otherwise I would make a fool of myself!

Mom said:? Think about it. You can only buy one biscuit for one dollar, and two steamed buns for one dollar.

Which is cheaper, biscuits or steamed bread? I know: the more things you buy with the same money, the cheaper that thing is. The price of three cakes is equivalent to five loaves of bread, but the price of one loaf of bread is lower than that of one cake, so bread is cheaper.
