Ms. Santos is Marketing Director of the Replica Model Train Company. She has just completed the brochure for the new line of 1890 Southern Pacific Railroad Trains.

There are six different cars in this line of trains: a passenger, a sleeper, a flat, a box, a refrigerator, and a dining car.

To promote the sale of the new line, the company is making a special offer. For $5, a customer will receive a train consisting of an engine and a passenger car, or an engine hooked-up to cars equal in length to a passenger.

How many different choices of trains are available for $5?

Engine- dining car - sleeper car & Engine - sleeper car - dining car are all considered different trains.
