Problem Statement:

A girl had 100 notebooks. She filled 28 notebooks in the first half of the year. How many notebooks did the girl fill in the second half of the year if she had 13 notebooks left by the end of the year?

Solution:

To find out how many notebooks the girl filled in the second half of the year, we can subtract the number of notebooks she filled in the first half from the total number of notebooks she had at the beginning of the year.

Let's calculate the number of notebooks she filled in the second half of the year:

Total number of notebooks = 100 Number of notebooks filled in the first half = 28 Number of notebooks left by the end of the year = 13

Number of notebooks filled in the second half = Total number of notebooks - Number of notebooks filled in the first half - Number of notebooks left by the end of the year

Number of notebooks filled in the second half = 100 - 28 - 13

Number of notebooks filled in the second half = 59

Therefore, the girl filled 59 notebooks in the second half of the year.
