Eric'snotebook has 30 pages. He wants to write a number on each page. How many digits will he write when he numbers all the pages in the notebook? 9 is it correct

I count 10 digits

1, 2, 3, 4, 5, 6, 7, 8, 9, 0

To find the total number of digits Eric will write when numbering all the pages in the notebook, we need to consider the number of digits needed to represent each page number.

The first nine pages will require one digit each (from 1 to 9), which adds up to 9 digits.

From page ten to page ninety-nine, a total of 90 pages, each page number will require two digits. So, there will be 90 x 2 = 180 digits for these pages.

Lastly, starting from page one hundred, each page will require three digits. Since Eric's notebook has 30 pages, the highest page number will be 130, so there will be 30 x 3 = 90 digits for these pages.

Now, let's add up the digits from each range: 9 + 180 + 90 = 279 digits.

Therefore, Eric will write a total of 279 digits when numbering all the pages in his notebook. So, the correct answer is not 9, but 279 digits.
