Just divide 245 by 55 to find out how many buses are needed.
245/55 = 4.4545 buses
This means that Corrine needs 4.45 buses to haul everyone on the trip. However, it is ridiculous to think that it would be possible to hire only .45 of a bus, so to have our final answer, we would round up to the nearest whole number.
Corrine should hire 5 buses to shuttle everyone to the trip.
