12. Elena added 32, 27, 14, and 48. She said that the answer was 121. Is this close to the correct answer?
Which statement shows how rounding can be used to explain why or why not?
A. Yes, this is close because 32 rounds to 40, 27 rounds to 30, 14 rounds to 20, and 48 rounds to 50. 40 + 30 + 20 + 50 = 140, and this is close to 121.

C. No, this is not close because 32 rounds to 30, 27 rounds to 20, 14 rounds to 10, and 48 rounds to 40. 30 + 20 + 10 + 40 = 100, and this is not close to 121.
