Answer: The answer is 500.
Step-by-step explanation:
784 rounded to the nearest hundreths is 800, because the number in the tenths place is 8. Anything over 4 is automatically rounded up. 349 is rounded down to 300, beacause the number in the tenths place is 4. When 300 is subtracted from 800, you will get 500. 800-300=500. So the estimated difference is 500.
