A 5-track lay-up yard has four tracks with three cars each and one track with four cars. How many additional cars can be stored?

To determine how many additional cars can be stored in the lay-up yard, we first need to calculate the total capacity of the tracks.

In the yard, there are four tracks that each accommodate three cars. Therefore, the total capacity of these tracks is:

4 tracks × 3 cars/track = 12 cars.

There is also one additional track that can hold four cars, adding another:

1 track × 4 cars/track = 4 cars.

Now, by summing up the capacities of all the tracks in the yard, we can find the overall storage capacity:

12 cars (from the first four tracks) + 4 cars (from the last track) = 16 cars.

The problem states that the yard is equipped to store cars; however, it does not specify how many cars are currently positioned in the yard. The question asks for the potential storage capacity without current cars in the mix.

If we assume the yard is empty at this point, we would consider that it can hold up to 16 cars in total. But if the objective is to calculate how many additional cars can be accommodated beyond the current configuration, it's essential to assume the yard already has cars being stored.

In typical scenarios where the problem requires maximum consideration,
