All of the citizens of a country have a eight-character or nine-character national identification code that is created using the 26 letters of the alphabet and the 10 digits from 0 to 9. What is the maximum number of citizens who can be designated with these codes?	Choose one.
A) 36^17
B) 35(36^9)
C) 37(36^9)
D) 35(36^8)
E) 37(36^8)
The number of possible 8-digit codes is 36^8.   The number of possible 9-digit codes is 36^9.   The total sum is 36^8 + 36^9 = 36^8(1+36) = 37(36^8)   The answer is 37(36^8).
