Question

In the toy bin there are a total of 248 vehicles.  If there are three times as many trains as cars, how many trains are there?

 

Write an equation with a variable to solve the problem.

 

I am a parent and don't understand how to solve this in order to help my child.

 

 

Answer 1

Let C = number of cars  (C is the variable) 

 

There are three times as many trains as cars, so number of trains = 3*C

 

Total of 248 vehicles, so 

 

C + 3*C = 248  (this is the equation to solve)

 

4*C = 248

 

C = 62  (this is the number of cars) 

 

So the number of trains is 3*C = 3*62 = 186 

 

You can check your answer by adding 62 cars + 186 trains to get 248 total vehicles.
