There are 20 students traveling. If every bus is full, it is most cost-effective to rent a bus with about 20 seats.

Because there are not many people in 20, it takes four or five small vehicles, and the cost of renting a car and gas, as well as the labor cost of drivers, are relatively high. Renting a 20-seat minibus just allows everyone to sit in one car, which is the best economy in terms of car use, driver and fuel cost, so renting a minibus is appropriate.

Tourism, noun explanation, travel, is to travel, go out to play, in order to reach other destinations, realize the travel process from local to different places in space.
