A library has 142 cds on its shelves. there are 11 shelves that have 8 cds on each shelf. the rest of the shelves have 6 cds on each shelf. how many shelves gave 6 cds

The answer is 9 shelves

Step-by-step explanation:

The total number of cds in the shelves 142

If 11 shelves as 8 cds each, then the 11 shelves as 11*8 cds = 88 cds

The cds let  now is 142 - 88 = 54

If the rest of the cds, i.e. the 54 cds are 6 cds each in a shelves,

Then the shelves containing them is 54/6 = 9
