Answer 1

Answer:  a.    320 books

Step-by-step explanation:

Given : The total number of books  were placed on the discount shelf for 70% off the regular price = 960

The fraction of books sold = $\dfrac{2}{3}$

Then, the number of books sold = $\dfrac{2}{3}\times960=640$

Now, the number of books remain on the discount shelf = $960-640=320$

Hence, the number of books remain on the discount shelf =320
