Final answer:
To find the number of wooden trains made, we can set up an equation and solve for 'x'.
Step-by-step explanation:
To solve this problem, let's represent the number of wooden trains as 'x'.
According to the given information, there are twice as many wooden cars as wooden trains. So, the number of wooden cars can be represented as '2x'.
We are also given that the total number of wooden vehicles made is 228.
Therefore, the equation that represents the given information is: x + 2x = 228
Simplifying the equation, we get: 3x = 228
Dividing both sides by 3, we find that x = 228/3 = 76
So, they made 76 wooden trains.
