Let x be the sell cost of each CD.
Assuming we sell all the CD's we are going to have a total of:
[tex]75x[/tex]of cash, to this we have to substract the cost of the crate, then we have:
[tex]75x-40[/tex]and we like this to be $185, then we have:
[tex]75x-40=185[/tex]Solving for x we have:
[tex]\begin{gathered} 75x-40=185 \\ 75x=225 \\ x=\frac{225}{75} \\ x=3 \end{gathered}[/tex]Therefore, the artis have to sell the CD's in $3
