The owner of a store buys some stationery at a price of 3 yuan, and the courier company will find some stationery and send it to the boss and charge a courier fee of 30 yuan. After calculation, the boss found that each piece of stationery must be sold at a price of 3.1 yuan to offset the courier fee, so he decided to increase the price to earn more profits.
