Answer:
There are a total of 495 people on the train
Step-by-step explanation:
Let's identify what we know:
1) The train has 3 passenger cars
2) Each passenger car has 4 columns, and each can accommodate 40 people.
3) All three passenger cars are full, but one of them has 15 additional people standing.
We can create a formula to model the problem:
x = ((3 x 4) x 40) + 15
x = the total number of passengers!
There are a total of 180 people sitting, and 15 additional people standing in one of the passengers cars, equaling a total of 495 passengers on the train.
