jill went to a library.she saw 23 boys and 20 girls reading.she also saw 17 people listening to a storyteller and 42 people using computers. how many people did jill see?

Answer 1

To find out how many people Jill saw at the library, we need to consider the unique individuals in each activity without double counting.

1. Boys reading: 23
2. Girls reading: 20
3. People listening to the storyteller: 17
4. People using computers: 42

The total number of individuals Jill could have seen, if none overlapped, would be:

\[ 23 \text{ (boys)} + 20 \text{ (girls)} + 17 \text{ (listeners)} + 42 \text{ (computer users)} = 102 \]

However, it's important to note that there may be some overlap among these groups (for instance, some boys or girls might also be listening to the storyteller or using computers). Since we don't have data indicating how many individuals are in multiple categories, we cannot definitively determine the total number of unique individuals she saw.

Thus, to provide an accurate answer, we need clarification on whether any of the groups overlap, as it can significantly affect the total count. However, if we assume there was no overlap and just wanted to find the total based on the numbers provided, the answer would be:

Jill could have seen up to 102 individuals if there were no overlapping.
