Idire 2. The State of CA also issues personalized license plates, which can be 2-7
characters in length, and the characters can be chosen from the set ( A, B, C.,
Z, 1, 2, ..., 9,7)
How many personalized license plates can CA issue that follow these rules? Hint:
Find the number of 2 character license plates, then 3 character plates, and so
on.

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

b is the correct answer
