Answer:
10000
Step-by-step explanation:
We have to round to the nearest ten thousand, so that mean multiple of 10000, for example, 20000, 30000, and so on. The criteria that we will use is if the thousand value if above 5000 we will round up to the next ten thousand.
because 899 is less than 5000, we have to stay in the same ten thousand multiple, in this case, 10000.
