Answer 2

Calculation of Books Repaired

To calculate the total number of books repaired over the three days, we need to add up the number of books repaired each day.

On the first day, 18 books were repaired.

On the second day, there were 9 more books repaired than on the first day. Therefore, the number of books repaired on the second day is 18 + 9 = 27 books.

On the third day, there were 23 more books repaired than on the first day. Therefore, the number of books repaired on the third day is 18 + 23 = 41 books.

To find the total number of books repaired over the three days, we add up the number of books repaired each day:

18 + 27 + 41 = 86 books.

Therefore, a total of 86 books were repaired over the three days.
