周末,我跟妈妈去逛商场,碰上商场搞打折促销活动。经过观察对比,我发现主要有“三种”促销方式,一是全场狂减40%,二是全场六折,三是满300元赠200元。妈妈得意地说:“这些衣服平常是不打折的,这次我得好好挑几件。”说完,妈妈选中了一条标价为800元的裙子。接着,她转向我说:“你不是学过折扣问题吗,快帮妈妈看一下,选择哪种打折方式最划算。”
Weekends, I went to the mall with my mother, run into the mall to discounts promotions. After observation and comparison, I found that there are mainly three kinds of promotions: one is a 40% reduction in the audience, the other is a reduction of 60% in the audience, and a third is a donation of RMB200 for 300 yuan. Mom proudly said: “These clothes are usually not discounted, this time I have to pick a few.” “Finish, my mother selected a skirt priced at $ 800. Then she turned to me and said: ”Did not you learn the discount problem, just look for the mom and choose which discount is the best."
