The purchase price of a piece of clothing is 120 yuan, and I wish the manager to increase the price by 50% to sell, but no one cares about it, so I have to sell it at a 20% discount on the list price. After selling, how much money can the manager earn?
一件衣服进价120元，祝经理提高50%的价格出售，结果无人问津，只好按标价打八折销售．卖出后，祝经理能赚多少钱？
