Yolanda arranges small square tables in a straight line. One person sits on each side of a table. How many people can sit at 4 tables?

• For 1 table: There are 2 people on the long sides and 2 people on the ends. Total = $2 + 2 = 4$ people.
• For 2 tables: There are 2 people on the long sides of each table ($2 \times 2 = 4$) and 2 people on the ends. Total = $4 + 2 = 6$ people.
• For 3 tables: There are 2 people on the long sides of each table ($3 \times 2 = 6$) and 2 people on the ends. Total = $6 + 2 = 8$ people.
• For 4 tables (as shown in the diagram): There are 2 people on the long sides of each table ($4 \times 2 = 8$) and 2 people on the ends. Total = $8 + 2 = 10$ people.

From the observations, for every additional table, 2 more people can be seated. This suggests a relationship involving multiplication by 2. The 2 people at the ends of the arrangement remain constant regardless of the number of tables.

Let $N$ be the number of tables and $P$ be the number of people.
The number of people can be calculated as:

For $N = 4$ tables:

This matches the example given in the problem statement.

The rule for the number of people ($P$) who can sit at $N$ tables is:

The specific questions for Activity 2 are not visible in the image, but this rule describes the pattern.
