Answer:
21,498.3
Step-by-step explanation:
This is the answer because:
1) The tenths place is right after the decimal point. In this case, the number is 2. The rounding number is right next to 2.
2) The rounding number is 5. Since the rounding number is greater or equal to 5, the number rounds up. Therefore, the number rounds to 3 from 2
