In a park, there are $n$ benches.
A maximum of 2 people can sit on each bench.
At this time, the maximum number of people are sitting on each bench and 8 people are walking in the park.
Which expression represents the total number of people in the park at this time?
\[
2 n \quad 2 n+8
\]
\[
2 n-8 \quad 8 n+2
\]
Answer
\boxed{2n + 8} is the expression representing the total number of people in the park at this time.
Step 1 ：There are n benches with a maximum of 2 people sitting on each bench, so there are \(2n\) people sitting.
Step 2 ：There are 8 people walking in the park.
Step 3 ：To find the total number of people, add the people sitting and walking: \(2n + 8\).
Step 4 ：\boxed{2n + 8} is the expression representing the total number of people in the park at this time.
