Train of thought: When calculating the chartering problem, when we encounter surplus, the final result is that we need to add 1. Because from the actual situation. Even if this boat is not enough for people, we still have to rent an extra boat for the rest.

Examples of chartering problems:

Question: 34 students are going to rent a boat to play. Each ship can accommodate up to five people. How many ships do you need?

Correct answer: 34÷5=6 (articles) ... 4 (person) 6+ 1=7 (articles)

A * * * needs seven ships.

Analysis: In the above question, when we rented six boats, but there are still four people who don't have a boat to sit on, we need to add an extra boat, so the answer is seven boats.

Extended data:

A mathematical problem with the same idea as "charter".

1, car rental problem.

Example of car rental problem:

Question: 23 students in a class are going for a spring outing. A taxi can take up to three people. How many cars does a taxi need?

Answer: 23÷3=7 (vehicles) ... 2 people 7+ 1=8 vehicles.

A: A * * * needs to rent eight cars.

Analysis: There are three people in each car, and the result is seven cars, but there are two people who don't have cars, so we need to add another car, and the final result is eight cars.
