Final answer:
To round 9985 to the nearest hundred, we check the tens digit; since it is 8, we round up the hundreds place to get a result of 10,000.
Step-by-step explanation:
To round 9985 to the nearest hundred, we need to look at the tens digit, which is 8. Since 8 is greater than 5, we round up the hundreds place. Thus, 9985 becomes 10,000 when rounded to the nearest hundred. This process of rounding up follows the conventional rounding rules where we round up if the next digit is 5 or more, and we round down otherwise.
