有一天，我和妈妈去购书中心买书，我买了一本笑话书，75元，打3折，75×0.3=22.5（元），我们又买了2件上衣，每件60元，都是打9折，60×0.9=54（元），54×2=108（元），我们还买了1条裤子130元。
One day, my mother and I went to the book center to buy a joke book. I bought a joke book, 75 yuan, 30% off, 75 × 0.3 = 22.5 yuan. We bought two more jackets, 60 yuan each, 90% off, 60 × 0.9 = 54 yuan, 54 × 2 = 108 yuan. We also bought a pair of pants, 130 yuan.
妈妈问我："今天总共花了多少钱？" 我说："22.5+108+130=260.5（元），今天总共用了260.5元。"
Mom asked me, "how much did it cost today?" I said, "22.5 + 108 + 130 = 260.5 yuan. Today I spent 260.5 yuan in total."
