Answer:

9

Explanation:

(just for confirmation)

For 11 shelves, 8 CDs each = 11 x 8 = 88 CDs in total

Amd rest shelves have only 6 CDs

So, for us to know, = the CDs left = total - no. Of cds

= 142 - 88 = 54

So the no. Of shelves = 54/6 ( bc we need to know the no. Of shelves)

So 54/6 = 9.

So 9 shelves
