Question

A bus makes a stop at 2:30, letting off 14 people and letting on 3. The bus makes another stop ten minutes later to let off 4 more people. How does the number of people on the bus after the second stop compare to the number of people on the bus before the 2:30 stop?

"A bus makes a stop at 2:30, letting off 14 people and letting on 3... number of people on the bus before the 2:30 stop?"...

-14+3-4
=-15

15 less people are on the bus after 2:30.

Hope this helps.
