Question

Juanito estimated that 31% of 517 is 204. is his estimate reasonable?

A. no because his calculation should be 30% of 520

B. no because his calculation should be 40% of 520

C. yes because his calculation should be 30% of 510

D. yea because his calculation should be 40% of 510

Answer 1

I think the answer is A.

Explanation:

31% rounds to 30%, and 517 rounds to 520, so we can eliminate B, C, and D. The answer is A, because A is the closest estimate to the real answer and it is the only answer left after the elimination. The real answer is 160.27.

Hope this helped!

Answer 2

The correct answer is B.
