Julien estimated his answer to be 35,000. His exact answer was 33,982. Is his answer reasonable? Why?

• No, because 33,982 is not close to his estimate of 35,000.

• Yes, because 33,982 rounds to his estimate of 35,000.

• No, because 33,982 does not round to his estimate of 35,000.

• Yes, because 33,982 is reasonably close to 35,000.

Answer explanation

While 33,982 would round to 34,000, that is still reasonably close to his estimate of 35,000.
