What is the sum of the number of authors and guests at the steam fair?

Explanation:
The idea here is to add counts from two separate groups. When two groups don’t overlap, the total number of people is simply their sum: authors plus guests. So you take the number of authors and add the number of guests. In this problem the two counts add up to 804, which is why the option showing 804 is the correct one. If there were any overlap (someone counted as both an author and a guest), you’d need to adjust to avoid double-counting, but with distinct groups, straightforward addition gives the right total.
