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.

Step 1 ：In a park, there are \(n\) benches.

Step 2 ：A maximum of 2 people can sit on each bench.

Step 3 ：At this time, the maximum number of people are sitting on each bench and 8 people are walking in the park.

Step 4 ：We need to find the total number of people in the park, which includes those sitting on the benches and those walking. We know that there are 8 people walking and 2 people sitting on each bench. We can represent the total number of people as a function of the number of benches, n.

Step 5 ：\(n = 5\)

Step 6 ：\(total\_people(n) = 2n + 8\)

Step 7 ：\(total\_people(5) = 2(5) + 8 = 10 + 8 = 18\)

Step 8 ：\(\boxed{18}\)
