Let’s analyze and solve the problem in the image.

Problem Breakdown:

1. The bus starts with 48 people.

2. At the library:

   • 24 people exit.
   • 3 people enter. After this, the number of people on the bus becomes: $48 - 24 + 3 = 27$

3. At the community center:

   • 3 people in each of the first two rows exit (which totals $3 + 3 = 6$).
   • No people enter. After this stop, the number of people on the bus becomes: $27 - 6 = 21$

Final Answer: There are 21 people on the bus after the stop at the community center.

Would you like further details or additional questions related to this scenario?

Here are 5 follow-up questions:

1. What is the net change in the number of people on the bus across all stops?
2. If two more people entered at the library, how many people would there be on the bus after the community center stop?
3. How would the total change if 5 people exited instead of 6 at the community center?
4. How many stops were involved in this scenario, and what changes occurred at each?
5. If the initial number of passengers was 60 instead of 48, how would the final count differ?

Tip: Always track the changes at each stop carefully to avoid calculation errors!
