In one city, 3,546 people attended a concert but in another city, 9,238 people attended the same band's concert. Estimate how many more people attended the concert in the second city by rounding to the nearest hundred and then subtracting.
First you round 9,238 to the nearest hundred which is 9,200, then you round 3,546 to the nearest hundred which is 3,500, subtract 9,200 from 3,500 and you would get 5,700.
