300.
First you find the hundred, which is 900. In rounding you're either going to stay at 900 or go up to the nearest 100, which in case is 1000. In order to decide whether to stay at 900 or go up to 1000 you need to look at the number just right, or the tens. In this case, since 8 is closer to 10 then it is 0, you would round up. So the nearest hundred is 1000. Since you already have 2,000 in your number, you add 1,000 to it, giving you the answer: 3,000.
850 to the nearest thousand is 1000
