In the question it is already given that the actual cost of each notebook is $1.20. For the weekend, the notebooks would sold at a discounted rate of $0.80
he
The amount of discount during the weekend = (1.20 - 0.80) dollars
                                                                       = 0.40 dollars
So the amount of discount given during the weekend is $0.40
Now we need to find the percentage of discount given during the weekend.
Then
Percentage of discount during the weekend = (0.40/1.20) 100
                                                                       = 0.33 100
                                                                       = 33
Then the percentage of discount given is 33%.

The sale is 33% off notebooks. This can be found by first subtracting .8 from 1.2

1.2-.8=.4    Now divide .4 by 1.2 to get your answer.

\(\frac{.4}{1.2}\)=.33

.33=33%

You can also solve this mentally because if you know your basic multiplication tables, 3*4=12 and so \(\frac{2}{3}\) of 12 would equal 8.
