Tyler used 2989 digits to number the pages of a book. How many pages does the book have?

I know that pages 1-9 use 1 digit, total number is 9
Pages 10-99 use 2 digits, total number is 180
Pages 100-999 use 3 digits, 900 pages= 2700
with 25 extra pages

Can you help me from here

pages 1 through 999 need 2889 digits

pages 1000 and up use 4 digit numbers

so 25 pages beyond 999

last page should be 1024
Need to be explained a little more
what about if he had 192 pages?
