Answer: 4000
Step-by-step explanation:
To estimate 4349.9 to the nearest 1000, you look at the digit in the thousands place, which is 4 in this case.
Since we want to round to the nearest 1000, we consider the hundreds place next to the thousands place. If the digit in the hundreds place is 5 or greater, we round up; if it is less than 5, we round down.
In this case, the digit in the hundreds place is 3, which is less than 5. Therefore, we round down the number to the nearest 1000.
So, 4349.9 rounded to the nearest 1000 is 4000.
