The boss received 100 yuan counterfeit money, and there was no income. The purchase price of rice is 60 yuan, and the boss has already spent 60 yuan to purchase it. The boss wants to sell this product at the price of 80 yuan. The income that the boss can get from the goods is 80 yuan. The counterfeit money of 100 yuan received by the boss cannot be used to buy goods or goods, and the counterfeit money has no value. The boss's loss is: 60 yuan's purchase price plus 100 yuan counterfeit money minus 80 yuan's selling price equals 80 yuan. So, the boss lost 80 yuan.
