THE SCHOOL’S RECORDS<br />
Kellie’s school celebrated its half-centenary this year. She joined with a group of her<br />
classmates to gather all the photographs <strong>and</strong> newspaper articles they could get from<br />
former students to put together a record of life at the school over the last 50 years. It<br />
was interesting to see how much life had changed over the years.<br />
When they had all of the materials arranged on the pages of the school’s collection<br />
of its records, Kellie pencilled the page numbers of each page to help later with<br />
drawing up the table of contents.<br />
1. After she had finished, Kellie told the others that she had written 687 digits. How many<br />
times had she written each of the digits 0–9?<br />
2. How many pages had she numbered?<br />
3. What page had she numbered when she was halfway through her task?<br />
4. How many digits had she written at this point?<br />
