Answer:
800
Explanation:
Take a look at the 10s place.
If the number is 5 or higher, the hundred value bumps up by 1.
If the number is 4 or lower, the hundred value stays where it is.
In this case, the tens value is 6, signifying the first rule.
7 + 1 = 8
Since you are rounding to the nearest hundred, the end result must be divisible by 100. In simpler terms, the last numbers must all be 0.
