Question

A train has 6 passenger cars and each car has 4 columns of seats and each column holds 50 passengers. If one of the cars has 25 empty seats, and the rest of the cars are full, how many passengers are on the train? Which of the following sets of equations correctly represents this situation?

Answer 1

Given:
The train has 6 passenger cars
Each car has 4 columns
And 1 column hold 50 passengers

So, total of seats will be = 6 * 4 * 50 = 1200

Now, there are 25 empty seats, 

therefore the correct equation will be : 

Number of seats per car: 4 × 50 = 200

Total number of seats: 200 × 6 = 1,200

Number of passengers: 1,200 − 25 = p
