A state had three letters followed by three digits as the format for license plates. In order to increase the number of plates available, the state changed the format to four letters followed by two digits. What is the positive difference between the number of plates available with the new format and the number of plates available with the old format?

26^3 *  1000   =  number of  plates  in old format

 

26^4 * 100  = number  of plates in new format

 

So

 

26^4 * 100  -  26^3 * 1000  =

 

28,121,600   =  difference
