Seven people arrive to dinner, but the circular table only seats six. If two seatings such that one is a rotation of the other are considered the same, then in how many different ways can we choose six people and seat them at the table?

well there is 7 ways to leave someone out so that makes 7 ways to choose 6 people.

there are 5! ways to seat those 6 people.

so maybe    7*5!   way.

It is probably wrong.    :)

Nah......that seems pretty logical to me, Melody.

7 different groups each seated 5! ways......

I agree with your answer......and we're NEVER incorrect on these counting probs, are we ???  LOL!!!
