A train arrives at the station with 150 passengers on board. \( \frac{2}{5} \) of the passengers get off the train in Seattle, and then 35 passengers board the train. How many passengers are on the train when it leaves the station?

To find out how many passengers are on the train when it leaves the station, we first need to calculate how many passengers get off in Seattle. \( \frac{2}{5} \) of 150 passengers is calculated as follows: \[ \frac{2}{5} \times 150 = 60 \] So, 60 passengers get off the train. Next, we subtract the number of passengers who got off from the original number of passengers: \[ 150 - 60 = 90 \] After that, 35 new passengers board the train: \[ 90 + 35 = 125 \] Therefore, the number of passengers on the train when it leaves the station is 125.
