Here all the numbers have three digits. 

The number 8 has replaced the unit. 

The middle digit can be any of the ten digits from 0 to 9.

In the hundredth place, any of the nine digits from 1 to 9 can be used.

According to the fundamental concept of counting, there are 10\times 9=90 numbers between 99 and 1000 that have 8 in the unit's location.
