First figure out Info needed So 142 people 6 drivers 2 vehicles of which are bus and vans Van:capacity of 10 Bus:capacity of 51 So plug in x for buses and y for vans x+y+6=142 Subtract 6 x+y=136 51 times 2 gives you 102 for the bus capacity so two buses x(2)+y=136 51(2)+y=136 102+y=136 Subtract 102 Giving you 34 y=34 4 vans because 34 divided by 10 is 3.4 but there is no 3.4 van so round up to 4 You end up needing 2 buses and 4 vans
