Answer 2

Calculation of the Total Number of Seats in the Bus

To calculate the total number of seats in the bus, we can use the information provided about the number of passengers and the number of remaining seats on both the trip to school and the return trip.

On the trip to school: - The bus had 12 passengers, and 9 seats were still available.

On the return trip: - The bus had 10 passengers, and 6 seats were still available.

To find the total number of seats, we need to add the number of passengers to the number of available seats on both trips.

Total number of seats = (Passengers on the trip to school + Available seats on the trip to school) + (Passengers on the return trip + Available seats on the return trip)

Total number of seats = (12 + 9) + (10 + 6)

Total number of seats in the bus = 37.

Please note that the specific layout of the seats (single or double) is not mentioned in the given information, so we cannot determine the exact number of single or double seats in the bus.
