Final answer:
There are 35 students on the bus now.
Step-by-step explanation:
To find the number of students on the bus now, we need to subtract the number of students who got off the bus from the total number of students on the bus after the additional students got on. Initially, there were 38 students on the bus. Then, 16 more students got on, bringing the total to 38+16=54 students. At the first stop, 19 students got off, so we subtract 19 from 54 to find that there are now 35 students on the bus.
