I bought a pair of shoes yesterday, and I used math when I bought them. The price of shoes is as follows: Original price of this pair of shoes: 290 yuan. Now we have an activity in the Spring Festival, the price is 203 yuan, with a 30% discount. In order to find out whether the discounted price is correct, it needs to be multiplied by 290×0.7=203 mathematically, so it is correct.

During the Spring Festival, my parents and I went to the supermarket to buy new year's goods. I bought two packages of Kebik, ***5 yuan: one package of butter cookies, 6 yuan: four packages of dried fish, 20 yuan: two packages of dried beef 14 yuan. Grandma bought a pack of washing powder 20 yuan: 1 fish 30 yuan, a pack of mushrooms 15 yuan, and two pieces of milk 40 yuan, and bought these things *** 140 yuan. Grandma took 300 yuan, and there was 160 yuan left after shopping. On the way home, we bought a Q gun. How much are two bags of football thunder 10 yuan and two pear eggs 2 yuan? 5+6+20+ 14+20+30+ 15+40+ 140+ 10+2=302.

My "lucky money" was collected before the New Year. The last time I collected it was when I watched the Spring Festival Gala on New Year's Eve. It's from my parents. The income is not small, 300 yuan. The first time 65438+ 10 month 10 is almost the same. We are in the factory. As soon as I finished eating, my grandmother gave me 200 yuan's "lucky money".
