## To determine the number of passengers on the commuter train halfway through its journey, we need to understand the given information.

The train consists of 8 cars and has room for another 84 passengers. Let's break down the problem step by step.

Step 1: Calculate the total capacity of the train
Since we are given that each car has the same capacity, we can find the capacity of one car and then multiply it by the number of cars.

Let's say the capacity of one car is represented by C, and the total number of cars is 8. Therefore, the total capacity of the train is 8C.

Step 2: Calculate the number of passengers on the train
We're told that the train has room for another 84 passengers. This means that the current number of passengers on the train is 8C - 84.

Step 3: Calculate the halfway point
Since we want to determine the number of passengers halfway through the train journey, we divide the current number of passengers by 2.

Thus, the number of passengers halfway through the train journey is (8C - 84)/2.

It's important to note that we need to know the capacity of each car (C) or have further information to determine the exact number of passengers halfway through the journey.
