Q: There were 50 people on the city bus. At the first stop, 15 people got off. At the next stop 8 people got off and 2 got on. At the third stop, 4 people got off and 3 people got on. How many people are on the bus after the third stop?
A: The bus started with 50 people – 15 who got off at the first stop = 35 people on the bus. At the second stop, 35 people on the bus – 8 who got off = 27 people. Then there were 27 people + 2 who got on = 29 people on the bus. At the third stop, 29 people on the bus – 4 who got off = 25 people on the bus. Then there were 25 people on the bus + 3 who got on = 28 people on the bus. The answer is 28.
