How many passengers are there at first? ** There are 50+16=<<50+16=66>>66 passengers at first.
How many passengers remain? ** Then 66 - 22 = <<66-22=44>>44 passengers remain.
How many passengers are there on the bus in total at the last station? ** Since 5 more passengers get on the bus there are 44 + 5 = <<44+5=49>>49 passengers on the bus.
