A train has 3 passenger cars and each car has 4 columns of seats and each column holds 40 passengers. If one of the cars has 15 people standing in addition to all of the sitting passengers, and the rest of the cars are full without anyone standing, how many passengers are on the train?

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.

the answer will be b x² +x-1
