In a survey of 2500 people who own a certain type of car 750 said they would buy that type of car again what percent of the people surveyed were satisfied with the car

That would be 30% an easy way to do it is think about what is 10% of 2500 and then multiply till you get the number you are looking for, in this case it is 250x3=750 and then you multiply the 10% as well so 30%
