In a classroom, the students are set up in the arrangement shown in the table. How many students are sitting at the 4 tables?

To determine how many students are sitting at the 4 tables, we would typically need the data from the arrangement table you’re referencing. If the total number of students at each table is provided, you would add them together to get the total number of students sitting at the 4 tables.

For example, if the tables have the following arrangement:

– Table 1: 5 students

– Table 2: 7 students

– Table 3: 8 students

– Table 4: 10 students

You would add them:

5 + 7 + 8 + 10 = 30 students.

However, without the specific numbers from your table, I cannot provide a direct answer. Please check the arrangement and perform this addition to find the total. If you have more detailed information, feel free to share!
