At the end of two weeks, the number of books left is: 19,999

This is reasonable.

The problem can be solved by applying simple mathematical operations such as addition and subtraction.

  • First, add the number of books sold in the first week and second week
  • Then subtract what you get from the total number of books the local store started with.
  • The result is the number of notebooks that were left after the two-week back to school sales.

Let's solve as follows:

  • Total number of notebooks they started with = 36,390
  • Number of notebooks sold during the first week = 7,424
  • Number of notebooks sold during the second week = 8,967

Number of notebooks sold in total = First week sales + second week sales

= [tex]7,424 + 8,967[/tex]

= 16,391 notebooks

Number of notebooks left after the two-week sales = [tex]36,390 - 16,391[/tex]

= 19,999 notebooks.

The answer is also reasonable because this is less than the total book we have from the start.

The number of notebooks left at the end of the sales period is 19,999.
