Calculation of the Change in the Number of Passengers

To calculate the change in the number of passengers, we need to subtract the number of passengers who entered the train from the number of passengers who exited the train. Let's calculate the change for each scenario:

1) In the first scenario, k = 70 and n = 80. To calculate the change, we subtract the number of passengers who exited the train (n) from the number of passengers who entered the train (k):

Change = k - n = 70 - 80 = -10 passengers exited the train.

2) In the second scenario, k = 72 and n = 72. Again, we subtract the number of passengers who exited the train (n) from the number of passengers who entered the train (k):

Change = k - n = 72 - 72 = 0 passengers exited the train.

Therefore, in the first scenario, the number of passengers decreased by 10, while in the second scenario, the number of passengers remained the same.
