Hi!

First, find the total percent of vehicles with at least 3 people.

15% + 7% + 3% = 25%

Now find 25% of 420

Set up a proportion and cross multiply to solve.


(x)/(420) (25)/(100)

25 * 420 = 10500

10500/100 = 105

The answer is 105 vehicles contained at least 3 people.

Hope this helped! :)
