Answer 1

To find out how many students in the seventh grade bike to school, we can use the information provided in the table.

From the table, we know:

- Total students in 7th grade who take the bus: 79
- Total students in 7th grade: 128
- Total students who bike to school: (total for both grades - total who take the bus)

The total number of 7th graders can be calculated by adding the number of students who take the bus and the number who bike to school:

Let \( x \) be the number of 7th graders who bike to school.
Then:

\[
79 + x = 128
\]

Solving for \( x \):

\[
x = 128 - 79 = 49
\]

Thus, the number of students in the seventh grade who bike to school is **49**.
