Answer:
The price of each CD before tax is $15.70
Step-by-step explanation:
Given that:
Number of CDs bought by Reuben = 5 
Cost of five CDs = $81.50 
Sales tax on each CD = $0.60 
Sales tax on 5 CDs = 0.60*5 = $3.00
Price of CDs without tax = 81.50 - 3.00 = $78.50
Price of each CD = 
Price of each CD = 
Price of each CD = $15.70 
Hence, 
The price of each CD before sales tax is $15.70
