Secondly, suppose everyone takes a cheap boat. If it happens to be full and there are no empty seats, then this rent method is the most economical; If it is not full, adjust it again. When adjusting, try to make the ship full.
Finally, tell the students that success is reserved for those who are prepared. Only by making full preparations can they gain something and succeed.
The strategy to solve the problem of chartering: first calculate what kind of ship (per capita rent) is cheap, and then consider renting this kind of ship first. If the ship is not full, make adjustments. Consider renting another kind of boat. When transferring the ship, it is necessary to fill the ship as much as possible so that there are no empty seats on the ship, and then determine the charter plan after calculating the total rent.
