For a 56-person tour group, there are 6-person buses and 8-person buses to choose from (each bus is different and there is no room). How many different car selection schemes are there? this

Because 7×8=56, seven 8-person buses are just right.

At the same time, three 8-passenger buses and four 6-passenger buses have the same passenger capacity, so four 6-passenger buses can be replaced by three 8-passenger buses.

So, the plan is:

7 8-seat buses;

4 8-seat buses and 4 6-seat buses;

1 8-seater bus and 8-seater bus
