Question

Cindy's mom asked her how many people were at the concert. Could she give an estimate or was an exact number needed?

Answer 1

Uhhh I'd assume estimate?

Answer 2

An Estimate would be better because the number of attendees doesn't always equal the number of available seats, so you'd say "About 20,000" instead of finding out exactly how many people are going, which would be very unlikely, so estimate.
