A script with a function that takes in an integer as argument and returns the number of letters it has

Letter-Counter

If the numbers 1 to 5 are written out in words: one, two, three, four, five, then there  are 3 + 3 + 5 + 4 + 4 = 19 letters used in total.  Write a program that takes in an integer and finds out how many letters were used  between that integer and 1    

NOTE: Do not count spaces or hyphens. For example, 342 (three hundred and forty-two) contains  23 letters and 115 (one hundred and fifteen) contains 20 letters. The use of "and" when writing out  numbers is in compliance with British usage.
