Question

200 adults who own a new car were surveyed to find out whether or not they've ever owned a new vehicle. 64% indicated that they have only owned used vehicles. Based on the results of the survey, about how many adults out of a group of 3500 haves owned a new vehicle?

Answer 1

The data given tells you that 36% of adults HAVE previously owned a NEW vehicle (100-64=36).

 

Applying this percentage to 3,500, by multiplying 0.36 by 3500, we ESTIMATE that 1,260 of those 3,500 people would have previously owned a new vehicle.
