When cooking this afternoon, my mother found that monosodium glutamate and old wine were gone. She gave me 10 yuan and a wine bottle, and told me to go to the shop in front to buy it. Aunt xiaodian said:? Lotus gourmet powder small package 2 yuan 5 cents a pack, old wine 1 yuan 3 cents a catty? . I asked for a pack of monosodium glutamate and 2 Jin of old wine and gave it to Auntie 10 yuan. My aunt asked me to do the math myself. How much should I pay? How much should I get back? I think two Jin of old wine is: 1 yuan 3 jiao+1 yuan 3 jiao =2 yuan 6 jiao. The monosodium glutamate is: 2 yuan 50 cents. Add it together and you have to pay 5 yuan/kloc-0 cents. 10 yuan -5 yuan 1 Angle =4 yuan 9 Angle, you should find 4 yuan 9 Angle. After I answered menstruation, menstruation praised me: The child is fine. Then, I will hurry home, give things and money to my mother and continue to finish my homework.

Comments by famous teachers:

This diary is well written! I also wrote the content of mathematics, and reviewed the knowledge of mathematics while writing, which is very good! Sentence fluency and clear thinking! Finally, here's a little problem? Continue to finish your homework? Does the teacher think that if the article should be said in front? I'm doing my homework? That's better. Overall good, come on!
