Serial numbers are counters and security features, but only affect a bill's value in specific cases. Normally the bill's series date and letter as well as its condition are much more important in determining a value. In this case the double letter in front of the serial number indicates it's a modern bill so it's only worth face value.
However, if the serial number is unusual in some way; e.g. low (00000010) or has an "interesting" pattern such as 13577531 or 12345678, there are collectors who will pay a premium.

As you have seen in many other postings, a bill's serial number almost never has anything to do with its value.
Worth about 4 to 10 dollar depending on condition
The "8894" serial number is a red flag. Regardless of denomination, nearly all Bank of the United States bills with that date and serial number are modern reproductions that have no value to collectors.
Depends on year and how low the serial number is.
The percentage of a partial bill really has little to do with its value. Any bill is worth its face value if it contains a complete serial number and any part of the other serial number.

The serial number alone isn't enough to assign value, but rather the series year and the condition. Without more information, it's assumed to be worth one dollar.
The value is more dependent on the year (series) of the bill. The serial number by itself isn't enough information.
Face value.

The value is determined by the series (date) and condition.
The serial number isn't really useful in giving a value. Post a new question and include information like the series (date) and condition.
