How many ways can you write two different letters chosen from
A B C D E F G H I J K L M N O P
so that they are in alphabetical order, and the first letter is a vowel?  For example, AF and EN count, but DE and KC do not.

A first letter  =  15 ways

E first letter = 11 ways

I first letter = 7 ways

O first letter = 1 way

 

So  34 total ways
