The first thing to ask is

seat

If there are enough seats and neither of the two comparison conditions is available, then we must first find the total number of students and teachers.

The number of teachers is known, and it is 18, with 60 teachers in each class and 9 classes. Calculate the number of students with 60×9 equal to 540. Then add 540 and 18, and the result is

Number of tourists

558 people.

Column type:

60×9+ 18

=540+ 18

= 558 (person)

After counting the numbers, let's look at the problem. The first question is whether there are enough seats, and then we will ask them.

seat

. It is known that each car has 45 seats, and * * * rented 12 cars, so 45× 12 was used to get 540 seats.

Column type:

45× 12 = 540 (piece)

The question is whether there are enough seats, so we compare the two and find that:

558>540

That is to say, there are not enough seats (interjecting: if there are enough seats, there will be no subsequent problems).

The second question is to tell you a strategy, that is, to answer: how can we get this 18 person to come with us? This question is simple. Just rent a smaller car (18 people rent 45 buses, which is a bit exaggerated).

Format, need to add subtitle (1)(2) and so on. The correct format is as follows:

(1) Total:

= 558 (person)

(2) Total seating capacity: 45× 12 = 540.
