In order to improve the income of taxi drivers, F city taxi company plans to change its taxi charging scheme. The company will charge a starting fee of 10 yuan for the first 5 kilometers or less, and 2 yuan per kilometer in the future; Instead of charging a starting fee of 6 yuan for the first 3 kilometers or less, a fare of 2 yuan per kilometer will be charged in the future,
The assumption that the area of F City is very small and many people don't take taxis for more than 3 kilometers is likely the basis for the company's belief that the plan can increase revenue.
