Frank bought 2 CDs that were each the same price. Including sales tax, he paid a total of 24.20 Each CD had a tax of 0.60 What was the price of each CD before tax?

11.5

Step-by-step explanation:

Frank paid a total of 24.2 for the 2 CDs, so, for each CD, he paid the total value divided by two:

Price of each CD = 24.2 / 2 = 12.1

Each CD had a tax of 0.6, so, to calculate the price of each CD before tax, we just subtract the price of each CD by the value of the tax for each CD:

Price of each CD before tax = 12.1 - 0.6 = 11.5

The price of each CD before tax is 11.5
