Answer 2

Calculation of the Total Number of Notebooks Sold

To calculate the total number of notebooks sold, we need to subtract the number of notebooks that remained in the store from the initial stock.

The initial stock of notebooks in the store was: - 12,100 notebooks in a ruled format (lined) - 9,300 notebooks in a grid format (squared)

After some notebooks were sold, the remaining stock in the store was: - 6,875 notebooks in a ruled format (lined) - 7,912 notebooks in a grid format (squared)

To find the number of notebooks sold, we can subtract the remaining stock from the initial stock for each format:

- Number of ruled notebooks sold: 12,100 - 6,875 = 5,225 notebooks - Number of grid notebooks sold: 9,300 - 7,912 = 1,388 notebooks

Therefore, the total number of notebooks sold is: 5,225 + 1,388 = 6,613 notebooks.
