Ariel · Answer 1

The number of CDs in Walter’s collection = x

The number of CDs in Brian’s collection = 3x

The total number of CDs in both collections = 144

Then

x + 3x = 144

4x = 144

x = 36

From the above deduction, we can conclude that the correct option among all the options that are given in the question is the last option or option "J".
