Liula [17]

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 = $\frac{Cost\ of\ CDs}{No.\ of\ CDs}$

Price of each CD = $\frac{78.50}{5}$

Price of each CD = $15.70

Hence,

The price of each CD before sales tax is $15.70
