Some students pass around a box of candy containing 25 pieces.Kendra took the first piece of candy. Each child takes a piece of candy as the box is passed around. Kendra also gets the last piece and may have more than the first piece. How many children are seated around the table?

So doesn't that mean there is more than one answer.
There could be 24 or less children.

You still haven't given us enough information.

We know that Kendra took the first and last pieces. Therefore, there are at least 24 children at the table. But -- she may have more than the first piece is unclear.

To determine the minimum number of children seated around the table, we need to assume that Kendra has only the first and last piece. In this case, there would be 24 children.

However, if we allow for the possibility that Kendra may have more than the first piece, there could be more than 24 children. For instance, if Kendra took the first and last pieces, as well as some pieces in between, then the total number of children would be greater than 24.

In summary, to determine the exact number of children seated around the table, we would need more information about whether Kendra took any additional pieces of candy apart from the first and last.
