A bus makes a stop at 2:30 it's letting off 15 people and letting on 9 the bus makes another stop 10 minutes later to let off 4
Snowcat [4.5K]
<u><em>Answer:</em></u>
The original number of passengers on the bus decreased by 10 after the second stop

<u><em>Explanation:</em></u>
Assume that the total passengers on the bus before 2:30 was x

<u>Now, at 2:30:</u>
15 passengers got off and 9 got on.
<u>This means that:</u>
number of passengers = x - 15 + 9 
number of passengers = x -6

<u>10 minutes later:</u>
4 passengers got off the bus
<u>This means that:</u>
number of passengers = (x-6) - 4
number of passengers = x - 10

<u>By comparing, we can note that:</u>
The original number of passengers on the bus decreased by 10 after the second stop

Hope this helps :)
