    Lisa likes going shopping very much. She often goes to clothes stores with her classmates on weekends. One day she sees a colorful sweater in the Fashion Clothes Store. It's a red-blue-yellow sweater. There is a card on it. It says 80 yuan. Lisa goes home quickly and collects(搜集) all her money. But she feels sad. She's only got 65 yuan.

    After two weeks, the Fashion Clothes Store has sweaters at very good prices------only 80%. Lisa thinks she can buy the sweater with 64 yuan. When she sees the card, it says 100 yuan.

    Some weeks later, the store says their sweaters are on sale. You can only pay(支付) 50% for the sweater. Lisa thinks she can get the sweater this time, because it only costs 40 yuan. But when she sees the card, she is very angry. It is 160 yuan.
