Hey there!
Here is your answer:
The proper answer to this question is "21 vehicles".
Reason:
Just divide 132 by 42 and that amount is how many cars you need to transport that amount!
132÷42=3.14285714
Now add 42 intill is gets to the amount of 132!
42+42+42=126
7+7+7=21
Therefore you would need 21 vehicles to transport 132 people!
If you need anymore help feel free to ask me!
Hope this helps!
