Answer:
820
Step-by-step explanation:
Here's how I estimated the numbers:
233=230
189=190
402=400
So the equation would be:
230+190+400
Which is equal to 820.
Hope this helped!

Answer:
820
Explanation:
Round to the nearest multiple of 10 (ex. 180, 190, 230, 240)
233 rounds to 230, going down.
189 rounds to to 190, going up.
402 rounds to 400, going down.
230 + 190 + 400 equals 820.
The question didn't specify, and the best way to estimate more accurately is by using multiples of 10.
