Answer: If Patty has lots of all digits from 0 to 9 except the digit 6, and she has only 241 of the digit 6, we need to find out how many pages she can number using the available digits.
Since she has 241 instances of the digit 6, she can use it to number a maximum of 241 pages.
For the remaining digits (0 to 5, and 7 to 9), she has an abundant supply, so she can use these digits freely.
Therefore, she can number a total of 241 pages in her scrapbook using the available digits.
