41...
guess, Joel has x CDs.
so,
$\frac{x-7}{3} =25$
or,x =82
again,mariella have $\frac{82}{2}$
=41

Blake has 25 CD's. I know that 75 divided by 3 is 25 but you had to subtract 7 from the number of CD's Joel had before you divided by 3, so you would have to add 7 to the 75 to get the number of CD's Joel has .Then you would multiply 82 and 2 to get Mariella's total CD's which is 164.
