Ziam is considering an offer to perform his own songs on a CD to be titled "Waiting There." In the past, he has written but not performed his music. If Ziam's royalty is 0.12 of the suggested retail price of $15.00, but 0.25 of the retail price is deducted for packaging before Ziam's royalty is calculated, how much will he receive for sale of the CD? Write your answer in the form of an equation and solve it.
