Alright, because we know that there are 36 people in the first car, and the second car has 3/4 of the amount of people in the first car, we can set up an equation, 36*3/4=x
To solve for x, what we can do is multiply 36 by 3, getting 108, then what you need to do is divide 108 by 4 to get 27, so there should be 27 people in the second car.
