In the first ten months of the year, people took out 427,113 books from the Brookton Library. The librarian would like to set a new record and have 500,000 books go out in one year. If 38,264 books are taken out in November, how many must go out in December to meet the librarian's goal?

34,623 books

Step-by-step explanation:

First, add the amount taken out in November to the amount from the first 10 months of the year.

427,113 + 38,264

= 465,377

Then, subtract this from 500,000:

500,000 - 465,377

= 34,623

So, to meet the librarian's goal, 34,623 books need to go out in December.
